Question

Define pseudopodia. Define villi. And tell the main function of both and tell difference to.

Answer 1

hi dear!!

pseudopodia is a temporary protrusion of the surface of an amoeboid cell for purposes of eating or moving. When the surface of an amoeba protrudes outward in order to reach food and then returns to normal, the protrusion is a pseudopodia.

villi  are small, finger-like projections that extend into the lumen of the small intestine. ... Villi increase the internal surface area of the intestinal walls making available a greater surface area for absorption.

hope this helps

good luck
