Pinocytosis and phagocytosis are accomplished by the:
Correct answer: C. Cell membrane
- A. Nucleus
- B. Mitochondria
- C. Cell membrane
- D. Endoplasmic reticulum
Explanation
The cell membrane or plasma membrane is very selectively permeable. It allows only a few substances to pass through it through diffusion. However, it can intake solid or liquid food particles needed by the cell in the form of food vacuole by phagocytosis and pinocytosis, respectively.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
