|
Answer» Correct Answer - C Spongilla belongs to phylum-Porifera, in which, choanocytes are the characteristic cells, these are absent in leech,dolphin and pengiun. These distinctive cells line the interior body walls of sponges. These cells have a central flagellum that is surrounded by a collar of microvilli. Choanocytes are versatile cells.

Planaria possesses high capacity ofA. metamorphosisB. regenerationC. alternation of generationD. bioluminescence |
|
Answer» Correct Answer - B Planaria is a flatworm belonging to phylum-Platyhelminthes. They are the simplest form of multicellular animal. They have high capacity of regeneration of new tissue at the wound site via cell proliferation (blastema formation) and the remodelling of pre-existing tissue to restore symmetry and proportion. This is due the neoblast cells. These cells are usually scattered through out the body and are able to participate in any type of development. The regenerative capacity of different body sections is an indicator of the presence of different numbers of neoblast cells. |
