  1. Phylum: Protozoa Phylum: Porifera Phylum: Cnidaria

  2. PROTOZOA Single celled organism Locomotion is effected by pseudopodia , cilia ,flagellum. Nutrition is autotrophic or heterotrophic. Reproduction – Asexual method or sexual method.

  3. PROTOZOA Flagellata sporozoa Ciliata Rhizopoda Euglena Amoeba Plasmodium Paramoecium

  4. AMOEBA

  5. PARAMOECIUM

  6. PLASMODIUM

  7. EUGLENA

  8. They are multicellular ,aquatic organism. Presence of canal system. ostia – spongocoel – osculam. The body wall contain spicules. Reproduction – Both asexual and sexual method. Example : sponges. PORIFERA

  9. SPONGES

  10. Structure of Sponge body

  11. COELENTERATA All animals are marine except Hydra. The body is radially symmetrical. The body wall contain two layers – Ectoderm and Endoderm. Inbetween ectoderm and endoderm , there is a mesoglea. Diploblastic animals . .Many coelenterate exhibit polymorphism. Example : obelia colony Presence of Nematocyst – Cells of defence – tentacle – When triggered ,poison is penetrated in to the prey. Reproduce both asexually and sexually method..
