Pinocytosis differs from phagocytosis in that pinocytosis
Correct answer: C. takes in dissolved substances in tiny droplets of fluid
- A. engulfs large solid particles
- B. occurs without any membrane
- C. takes in dissolved substances in tiny droplets of fluid
- D. occurs only in plant cells
Explanation
Pinocytosis brings in small vesicles of extracellular fluid with dissolved solutes, while phagocytosis handles solid particles. Both require the plasma membrane to fold inward, and both occur in animal cells, so neither of those features separates them.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
