Question:

Match the column I with column II and choose the correct option.

Options:

1. 2 3 5 4 1
2. 2 5 3 4 1
3. 1 3 5 4 2
4. 1 5 3 4 2

Solution:

The body of porifera (sponges) is organised in such a way, so that they form a complex system of pores and canals called canal system. This system helps in regulating the flow of water within them e.g., Sycon. Aschelminthes possess jointed appendages e.g., Ascaris. Annelidans possess metameric, segmentation in body e.g., earthworm. Athropodans possess jointed appendages in each segment of their body e.g., cockrach. Echinoderms possess water vascular system or ambulacral system e.g., Asterias or starfish.
