Question

A cell conducts endocytosis by _____.

Answer 1

active transport osmosis pinocytosis diffusion phagocytosis exocytosis

Answer 2

Endocytosis is an energy-using process by which cells absorb molecules (such as proteins) by engulfing them. Thus they use pseudopodia for that

Answer 3

well given your possibilities, there is a right answer to your question.

let's say that endocytosis means that a cell brings big molecules (big means at least protein-sized objects) into its own cytosol / periplasm. this is done by building vesicles with the cargo (a 'mouth-full').

active transport, pinocytosis and phagocytosis are all mechanisms by which a cell can 'devour' something. since pinocytosis is the science word for drinking, this accounts for water. active transport *can* move proteins, but there are no vesicles involved here.

finally, phagocytosis meets all criteria. this is the right answer.

for your next question, please try to go at it yourself first, so that we can 'guide' you through to the right answer!
