Question

explain tube feet and false feet ?

Answer 1

The tube feet in a starfish are arranged in grooves along the arms. ... Tube feet allow these different types of animals to stick to the ocean floor and move slowly. Tube feet consist of two parts: ampullae and podia. Ampullae contain both circular muscles and longitudinal muscle, whereas the podia contain the latter only.

An amoeba, sometimes written as "ameba", is a term generally used to describe a single celled eukaryotic organism that has no definate shape and that moves by means of pseudopodia. Pseudopodia or pseudopods are temporary projections of the cell and the word literally means "false feet".
