Question

during passive transport, molecules move from lower concentration to higher concentration, unlike in active transport.
amoeba is an example of active transport. endocytosis in amoeba helps it to take in food (from an environment of higher concentration) from the surroundings and then inside its vacuole (lower concentration)
so how can we say active transport occurs in amoeba?

Answer 1

Explanation:

The whole cell works during the process. It is not just some membrane proteins taking in a couple of molecules as in active transport. ... Once contact is made, the amoeba slowly wraps its cell membrane around the object. When the membranes reach out for the prey, they are called pseudopodium.
