Question

multiple choice question
phagocytosis is one of the three main types of ______.

○ exocytosis
○ pinocytosis
○ endocytosis
○ passive transport

Explanation:

Phagocytosis (cell eating), pinocytosis (cell drinking), and receptor - mediated endocytosis are the three main types of endocytosis. Exocytosis is the opposite process of endocytosis (releasing substances out of the cell), and passive transport is the movement of substances across the cell membrane without energy input (like diffusion, osmosis), which is different from endocytosis. So phagocytosis is one of the three main types of endocytosis.

Answer:

C. endocytosis
