"lage rho exam clear karo"....@wesome sir...👌😎
very nice explanation sir 👌👍
sir u said that if question comes that which phylum has regeneration capacity then and would be platyhelminthes but porifera also has regeneration capacityand cnidaria has remarkable capacity of regeneration so what should be done??
sir ctenophora me radial symmetry hoti h ha biradial ya dono terms same h plz tell me sir it's too confusing

  2. WHAT TO STUDY? Basis of Classification Levels of Organisation . Symmetry .Diploblastic and Triploblastic Organisation (Germ Layer) . Coelom Segmentation Notochord . Classification of Animals . Phylum Porifera Phylum Colenterata . Phylum Ctenophora . Phylum Platyhelminthes .Phylum Aschelminthes Phylum Annelida Phylum Arthropoda . Phylum Mollusca Phylum Echinodermata Phylum Hemichordata . Phylum Chordata

  3. * Class Chonarichythyes * Class Amphibia . Class Aves Class Cyclostomata Class Osteichthyes Class Reptilia . Class Mammalia Key Point of Animal Kingdom

  4. Phylum - Ctenophora Sea walnuts or Comb jellies Habitat - Exclusively marine Symmetry - radially symmetrical. Level of organization - tissue level of organization and diploblastic. Special organ - eight external rows of ciliated comb plates, which help in locomotion. .

  5. Digestion - both extracellular and intracellular. Special property - Bioluminescence (the property of a living organism to emit light) . Reproduction - Bisexual animals (Hermaphrodites) Only sexual reproduction. Fertilisation-external Development - indirect development. Examples: Pleurobrachia and Ctenoplana.

  6. Phylum - Platyhelminthes Body shape - They have dorso-ventrally flattened body, hence are called flatworms Habitat - Mostly endoparasites found in animals Symmetry - bilaterally symmetrical. Body organization - organ level of organisation and triploblastic Body cavity - Absent, acoelomates. pecial structures - Hooks and suckers are present in the parasitic forms for support and absorption. Some of them absorb nutrients from the host directly through their body surface.

  7. Excretory cells - flame cells help in osmoregulation and excretion . Reproduction - Bisexual animals (Hermaphrodites). Fertilisation - Internal. Development - Indirect through many larval stages. Some members like Planaria possess high regeneration capacity.(NEET/AIPMT) Examples: Taenia (Tapeworm), Fasciola (Liver fluke), Planaria
