Exocytosis is the process by which a cell
Correct answer: A. releases materials in vesicles that fuse with the plasma membrane
- A. releases materials in vesicles that fuse with the plasma membrane
- B. takes in fluid droplets from its surroundings
- C. pumps ions against their concentration gradient
- D. divides its cytoplasm during cell division
Explanation
Secretory vesicles from the Golgi move to the surface and merge with the membrane, discharging their contents outside, which is how enzymes, hormones and neurotransmitters leave the cell. The reverse process is endocytosis, and ion pumping is active transport.

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.
