Question

15 what is the role of the cytoskeleton in eukaryotic cells?
a. storing genetic material.
b. providing structural support and facilitating intracellular transport
c. generating energy.
d. synthesizing lipids and proteins.

Explanation:

The cytoskeleton is a network of protein filaments in eukaryotic cells. It gives the cell shape (structural support). Also, motor proteins move along the cytoskeleton filaments for intracellular transport (like moving vesicles).

• Option a: Storing genetic material is the role of the nucleus (with DNA).
• Option c: Generating energy is mainly by mitochondria (cellular respiration) or chloroplasts (in plants, photosynthesis).
• Option d: Synthesizing lipids (smooth endoplasmic reticulum) and proteins (ribosomes, rough endoplasmic reticulum).

Answer:

B. Providing structural support and facilitating intracellular transport
