Current Question (ID: 13509)

Question:

Match the following cells/structures with their phyla of origin 1) Flame cells (i) Coelenterata 2) Choanocytes (ii) Platyhelminthes 3) Cnidocytes (iii) Ctenophora 4) Comb plates (iv) Porifera

Options:

1. 1-(i), 2-(iv), 3-(ii), 4-(iii)
2. 1-(iii), 2-(ii), 3-(iv), 4-(i)
3. 1-(ii), 2-(iv), 3-(i), 4-(iii)
4. 1-(ii), 2-(iii), 3-(i), 4-(iv)

Solution:

Flame cells are concerned with excretion in Platyhelminthes. Choanocytes are the characteristic cells of Porifera. Cnidocytes are defensive and anchorage cells in Coelenterata. Comb plates are locomotory structures found in Ctenophora.
