sir in this vedio u taught us that in diploblatic there are three layers but in actual there are two layers plz explain that which one is correct

yes, they have two layers thats why they are called as diploblastic. But they have "Mesoglea" (jelly like undifferentiated layer) layer which is not specialized to form any particular tissue.

  1. Class 11th 04. ANIMAL KINGDOM NEET/AIIMS ANMOL SHARMA


  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 - Porifera (Sponges) Habitat - Aquatic - generally marine, some are fresh water. .Symmetry - mostly asymmetric. (PMT) Organization level multicellular with cellular level of organisation. . Canal system Sponges have a water transport or canal system. Water enters through minute pores (ostia) in the body wall into a central cavity, spongocoel, from where it goes out through the osculum. (AIPMT2008) This pathway of water transport is helpful in food gathering, respiratory exchange and removal of waste


  5. Special cells - Choanocytes (NEET 2017) or collar cells line the spongocoel and the canals. These cells are flagellated Digestion - Intracellular Skeleton - Made up of spicules or sponging fibres * ReproductionBIsexual or hermaphrodite animals. * Sponges reproduce asexually (fragmentation) and sexually Fertilisation - Internal . Development - Indirect having a larval stage which is morphologically distinct from the adult Examples: Sycon (Scypha), Spongilla (Fresh water sponge) and Euspongia (Bath sponge


  6. Phylum - Coelenterata (Cnidaria) Habitat - Aquatic, mostly marine, sessile or free- swimming, Symmetry - Radially symmetrical Special cells - cnidoblasts or cnidocytes (which contain the stinging capsules or nematocytes) present on the tentacles and the body. Cnidoblasts are used for anchorage, defense and for the capture of prey. . Source :- This image is from NCERT Textbook Page no. 50


  7. .Level of organization - tissue level of organisation . Body Cavity - Absent, central gastro-vascular cavity .Digestion - both extracellular and intracellular. and diploblastic. present with a single opening, hypostome Skeleton - Some of the cnidarians - corals have a . Basic body forms - Cnidarians exhibit two basic .Polyp It is a sessile and cylindrical form like Hydra, .Medusa - it is umbrella-shaped and free-swimming skeleton composed of calcium carbonate. body forms called polyp and medusa. Adamsia, etc like Aurelia or jelly fish.


  8. Alternation of generation (Metagenesis) some cniderians exist in both polyp and medusa forms and exhibit alternation of generation (Metagenesis), i.e., polyps produce medusae asexually and medusae form the polyps sexually (e.g., Obelia). >Polyp Phase sexually Alternation of generationAsexually Medusa Phase SourceThis image is Self Made For Learning Purpose


  9. .Examples: Hydra, Aurelia (Jelly fish), Obelia (Sea Fur), Physalia (Portuguese man-of-war), Adamsia (Sea anemone), Pennatula (Sea-pen), Gorgonia (Sea-fan) and Meandrina (Brain coral). (aj tb) Aurelia(Medusa) Adamsia(Polyp) Source :- This image is from NCERT Textbook Page no. 50
