It alternates with multicellular saprophytic/autotrophic, In this post, we are providing Complete Notes on Biology for the upcoming SSC CGL Exam and other competitive exams. The multicellular female gametophyte is also retained within megasporangium. Male gamete is more active and female gamete is less active and bigger in size, e.g., Some species of Chlamydomonas. Acetabularia (umbrella plant) has unicell upto 10 cm long with distinction of nucleus containing rhizoid, elongated stalk and umbrella like cap. Important notes of Biology for NEET for Plant Kingdom are useful for all aspirants preparing for entrance exams including NEET. The zygote develops into embryo and the primary endosperm nucleus develops into an endosperm. Phylogenetic System of Classification Male and female gametophytes do not have independent free-living existence. The male gametes released from the antheridia and reach to the mouth of archegonium. NCERT Solutions, NCERT Exemplars, Revison Notes, Free Videos, CBSE Papers, MCQ Tests & more. Some of them are also found in close association with fungi (lichen) and animals {e.g., on sloth bear). Angiosperms This is called siphonogamy. How to Create Worksheets using Test Generator? Endosperm provides nourishment for growth of seedling at the time of seed germination. (ii) The classification is outdated as the habit is used as . Within ovules are present highly reduced female gametophytes termed. (i) This is not helpful in plant identification. An embryo stage is not present. They ranges in colour from olivt green to various shades of brown depending upon the amount of the xanthophyll pigment, fucoxanthin present in them. Fucus, an alga is diplontic. Advantages It lies naked or exposed. At last compare my handwritten notes and the NCERT, and try to prepare your handwritten notes, if time permits. Hence, these help in biological succession. The plant body (thallus) is without differentiation. A distinct male gametophyte may not be present. Classification of Pteridophytes There are about 250000 species of angiosperms in the nature. For example, sporocarps of Marsilea is edible. i.Class-Chlorophyceae (Green Algae) In sexual reproduction, the sex organs antheridia and archegonia are produced at the apex of the leafy shoots. (ii) This system is in conformation with the modern views of phylogeny. The female sex organs in a flower is the pistil or the carpel. Content Guidelines 2. The pteridophytes are further classified into four classes A colony for fixed number of individual unicells (Volvox) is called coenobium. It occurs by fragmentation, tubers, stolons, adventitious branches, etc. Classification of Angiosperms It occurs by a number of accessory spores, such as zoospores aplanospores, akinetes, carpospores, etc. External Features The plant body is sporophyte and differentiated into root, stem and leaves. NEET toppers Biology handwritten notes contain 6 books. Each pollen grain germinates on the stigma forming a pollen tube that carries two male gametes to the embryo sac, growing through the tissues of stigma and style. (iii) Sphenopsida (Equisetum) (i) Root is absent. The leaves may be simple or compound. (d) Sporophyte The sporophyte in mosses is more elaborate than that in liverworts. (i) The angiosperms are major source of food, fibers, spices and beverages. Pyrenoids contain protein besides starch. Because of the involvement of above mentioned two events, it is known as double fertilisation. The sex organs in bryophytes are multicellular, the male sex organs in bryophytes is called antheridium (which produces biflagellate antherozoids) and the flask-shaped female sex organ is called archegonium (produces a single egg). (ii) Unrelated organisms are kept in separate groups. Shivanshu Kamal Namdeo. The haploid phase is either microscopic or represented by gametes only (e.g., Fucus). The natural system of classification is based on natural affinities among the organisms. The cellulosic wall of vegetative cells is usually covered on the outside by a gelatinous coating of algin. This is very helpful it helps me too much …. Gymnosperms Anisogamy It is the fusion of structurally dissimilar gametes, which differ in size and – behaviour. They remain within the sporangia retained on the sporophytes. Reproduction Admin 21 Jun 2019. Cell wall contains cellulose and poly-sulphate esters. The gametophyte may be produced directly or first from a juvenile stage called protonema. Zygotes do not undergo reduction division immediately instead, they produce a multicellular body called sporophyte. Fucus and Laminaria are rich source of Iodine. Fertilisation Angiosperm are found in wide range of habitats, from the land to up to 6000 m in Himalayas or Antarctica and Tundra, dry hot deserts, cold deserts, tropics, fresh water up to 60°C, underground, over other plants as parasites, saprophyte, etc. Usually aquatic but a few are also found in moist terrestrial habitats like tree trunks, wet rocks, moist soil, etc. NEET Study Material Free Download Pdf Notes 2020, Allen Study Material , Minor And Major Test Series, Aakash Medical NEET/AIIMS Modules, Mock Out of which one is enclosed within the megasporangium (nucellus) and develops into a multicellular female gametophyte, bearing two or more archegonia of female sex organs. NEET toppers Biology handwritten notes contain 6 books. The gemmae becomes detached from the parent body and germinate to form new individuals, During sexual reproduction, male and female sex organs are produced either on the same or on different thalli. * The brown algae that are used as food are Laminaria, Nerocystis, Macrocystis, Alaria, etc. The plant kingdom, Angiosperms, Structural organization in plants, Cell Division, Cell-The Unit of Life. (Hi) The algae Gelidium and Gracilaria are used to produce agar, which is used in preparation of ice creams and jellies. A distinct male gametophyte is present.

The polar nuclei eventually fuse to produce a diploid secondary nucleus. Economic Importance of Gymnosperms The main plant body is a sporophyte which is differentiated into true root, stem and leaves. The members of Rhodophyceae are commonly called red algae because of the predominance of the red pigment,i.e., r-phycoerythrin in their body. 5. 3. have long been used as fuel. Seeds Fertilisation Haploid spores are produced by this plant body by meiosis. These are attached to the substratum by unicellular or multicellular rhizoids. Reproduction These are simple or compound. 1. The important salient features of algae are given below (i) Life Cycle Isomorphic alternation of generation is found in some brown algae, e.g, Ectocarpus, Dictyota. Spores * Brown algae are collected from sea shores and used as manure. In heterosporous ferns, the female gametophyte depends on food stored by the megaspore. The smallest angiosperm is water plant Wolffia and tallest is Eucalyptus regnans (100 mand above). These in turn, divide by mitosis to form a haploid plant body once again. Antheridium is sessile and surrounded by a single layered jacket. Botany-II: covers the following topics Bryophytes The largest kelps are Macrocystis (40-100m) and Nereocystis (20-30 m). Resin is distilled to obtain turpentine and resin. Made by. It is also used in clearing liqueurs and finishing leather, etc. CBSE quick revision note for class-11 Mathematics, Physics, Chemistry, Biology and other subject are very helpful to revise the whole syllabus during exam days. An anther contains four microsporangia where microspore mother cells become differentiated to form four microspores, each developing into a pollen grain. (i) Chromosome number is constant for a species, e.g., 46 in man, 48 in apes and potato, 20 in maize, 16 in onion and 8 in Drosophila. However, surface conduction through capillarity is an important mechanism of water supply to aerial parts. Aristotle is known as father of Zoology. Number and codes are assigned to all the characters and the data are then processed. Gymnosperms are those plants in which the ovules are not enclosed inside the ovary wall and remain exposed before and after fertilisation. Some algal forms are also found in moist habitats like wet rocks and soil, tree trunks, etc. The main plant body produces gametes, hence it is called gametophyte. Mosses (Bryopsida) grow in dense mats over moist shady places, especially during rains. * The red algae like Porphyra, Chondrus, Rhodymenia, Centerella and Bostrychia are used as food in various parts of the world. These are algin (brown algae) and carrageenan (red algae) which have many commercial uses. independent but short lived haploid gametophyte. Fusion of male gamete with the egg present in the archegonium result in the formation of zygote. (i) This system use only few superficial characters (i.e., habits, numbers, colours and shapes of leaves, etc) which leads to many orgarfisms grouped together, Alteration of Generation Plant Body Morphology It forms tap root system. Stem develops from plumule. The overview of this classification is demonstrated here in the flowchart. Some algae may store food in the form of oil droplets also. (ii) Lycopsida (Selaginella and Lycopodium) Each embryosac contains a three celled eg® apparatus consisting I of one egg cell and two synergids, three antipodal cells (at the i opposite end) and two polar nuclei (in the central cell). Haplodiplontic It has an eukaryotic plant cell structure. (iii) It does not demonstrate natural and phylogenetic relationships. Bryophytes in general are of little economic importance. (c) Reproduction It may occur both by asexual and sexual means. CBSE Class 11 Biology Handwritten Notes By Kota are as per guidelines of the NCERT syllabus. Phloem contains sieve tubes and companion cells in regard to gymnosperms which do not have companion cells. Many of the gymnosperms live for more than 4000 years, e.g, Pine (Pinus), redwood {Sequoia). Male organs appear cup-shaped, while female organs are bud-like. They improve mineral content of soils. (b) Heterogamy In this process, fusion occurs between morphologically as well as physiologically different gametes. Algae are chlorophyll-bearing, simple, thalloid, autotrophic and largely aquatic (both freshwater and marine) organisms. Both phases are multicellular. Examples Cycas, Pinus, Ginkgo, Ephedra, Gnetum, Vaucheria, Cedrus, Abies, etc. Water is required for fertilisation of male and female gametes. However, they dilfer in their dominant phases. Advantages 3. Sporophyte is dependent on gametophyte for nourishment. ii. Chapter 2 - Biological Classification. Fungi and members of the Monera and Protista having cell walls have not been separated form Plantae, the earlier classifications kept them in the same kingdom. All Notes are well organised and are ideal for pre-medical exams like NEET-UG, AIIMS, JIPMER, CBSE and ICSE Board exams. Phycobilins are water soluble and are of two types, i.e., red-coloured phycoerythrin and blue-coloured phycocyanin. Water is required for transfer of antherozoids. • Asexual Reproduction It occurs by fragmentation of thalli or by the formation of specialised structures called gemmae (sing, gemma). (f) Food Reserve It remains in the form of complex carbohydrates such as laminarin or mannitol. Each stamen has two main parts, i.e., a slender filament with an anther (at the tip). The bryophytes are generally classified into two main groups The cells which produce spores are called sporangia. (b) Thallus The red thalli of most of the algae are multicellular. The reserve food material is starch. Economic Importance of Angiosperms It is carried out by quantitative assessment of similarities and differences in order to make objective assessments.

Eukaryotic, multicellular, chlorophyll containing and having cell wall, are grouped under the kingdom Plantae. (iii) Evolutionary basis is neglected. The dominant photosynthetic phase is a gametophyte produced by haploid spores. Some mosses grow in desert bogs and streams. Differences between Male Gametophyte of Pteridophyte and Gymnosperms After meiosis, spores are produced within the capsule. The male produced is non-flagellated, called as spermatium. It is partially embedded. Spores germinate to produce multicellular thalloid. Vascular Tissues ii. myCBSEguide | CBSE Papers & NCERT Solutions. Genera like Selaginella and Salvinia which produce two kinds of spores, macro (large) and micro (small) spores; such plants are called heterosporous. Here you will find a collection of handwritten notes of Dr. Neela Bakore Mam which is absolutely free to download. Different plant groups and individual have different features in their life cycle Gametophyte Vegetative reproduction is by the fragmentation and budding in secondary protonema. Some cells of the sporophyte undergo reduction division (meiosis) to produce haploid spores (which germinate to produce gametophyte). It helps in sealing female cones after pollination, scale leaves around leaf bases and apical buds. After watching the videos read the NCERT thoroughly and underline and highlight the important points. (iii) Mosses along with lichens are the first organisms to colonise rocks. There are about 7000 species in this class. This system is based on fossil records of biochemical, anatomical, morphological, physiological, embryological and genetical. The revision notes help you revise the whole chapter in minutes. Ciass-Rhodophyceae (Red Alqae) Xylem consists of tracheids and phloem is made up of sieve cells and albuminous cells. Cytotaxonomy is based on cytological information like chromosome number, structure, behaviour and type of chromosomes. Life cycle is various- haplontic, diplontic or diplohaplontic. Artificial System of Classification Botony:3 Books covers the following topics. This feature leads to the formation of different plant bodies haploid and diploid. (g) Flagellation These contain heterokont flagellation with one smooth (whiplash) and one tinsel flagella. The gemmae become detached from the parent body and germinate, forming new individuals. Angiosperms have vessels in xylem. Each embryo-sac has a three-celled egg apparatus – one egg cell and two synergids, three antipodal cells and two polar nuclei. Difficulty - Average. Bryophytes do not attain great heights. It is present in Bryophytes and Pteridophytes. These notes will certainly save your time during stressful exam days. There are parts where I've written in pencil so it's fairly hard to read, or other places where I've condensed the words too Morphology of Flowering Plants – Important Points, Summary, Revision, Highlights Morphology of Flowering Plants The Root. Vascular Tissues All seed bearing plants, gymnosperms and angiosperms follow this pattern of life cycle. Economic Importance of Pheophyceae The gametophytes bear male sex organs called antheridia and female sex organs called archegonia. The egg secretes a chemical which attracts spermatozoids. Carpel or pistil is called the female sex organ of the flower. Pollination One sperm fuses with an egg and produces a diploid zygote. Sex Organs First, watch the videos to learn concepts and important data, for this, YouTube channels very good. Taxol is an anticancer drug obtained from Taxus. This kind of life cycle is termed as diplontic. Meiosis in the zygote results in formation of haploid spores. Sexual reproduction is performed by isogamy, anisogamy and oogamy. 2nd Year Quick View.

Lycopodium is used in treatment of rheumatism and disorders of lungs and kidneys. Angiopteris and Alsophila have starchy pith eaten by natives of Australia. (i) Some mosses provide food for herbaceous mammals, birds and other animals. Fungi and members of the Monera and Protista having cell walls have not been separated form Plantae, the earlier classifications kept them in the same kingdom. Meiosis in zygote results into haploid spores to form gametophytes, which is the dominant vegetative phase. (v) Marchantia has medicinal properties to cure lungs and liver infections. The gametes fuse and produce a diploid zygote, that represents sporophytic generation. Most of the members have one or more storage bodies called pyrenoids located in” the chloroplasts. For example, the presence of raphides has been found to be common in 35 families of plants. * Fucus and Laminaria are rich in iodine. Movement and locomotion Handwritten notes by Dr. Neela Bakore Mam (a) Plant Body The predominant stage of the life cycle of a moss is the gametophyte which consists of two stages the first stage is the protonema stage which develops directly from a spore. (b) Cell Organisation These are unicellular, colonial, coenocytic and multicellular forms. There are about 13000 species of pteridophytes have been reported. Bryophytes commonly grow in -moist, shaded areas in hills. The system was initiated by Engler and PrantI (1887-1899) in Die Naturalichen Pflanzefamilien.
