Question

13 what is the primary function of vesicles within a cell?
a. storing genetic information.
b. transporting materials between organelles.
c. synthesizing proteins and lipids.
d. providing structural support.

Explanation:

Vesicles are small membrane - bound sacs in cells. They bud off from one organelle (like the endoplasmic reticulum or Golgi apparatus) and fuse with another (e.g., a lysosome or the plasma membrane). This process is crucial for transporting substances such as proteins, lipids, and other molecules within the cell.

• Option a: Storing genetic information is the function of DNA (in the nucleus for eukaryotes).
• Option c: Synthesizing proteins is mainly done by ribosomes (often attached to the endoplasmic reticulum), and lipid synthesis occurs in the smooth endoplasmic reticulum.
• Option d: Providing structural support is a role of the cytoskeleton (e.g., microtubules, microfilaments).

Answer:

B. Transporting materials between organelles.
