Correct Answer: B
Explanation:
). The danger in picking vacuole for the answer is that it is the vacuole and the water in it that create turgor pressure, which does indeed provide for cell support in plant cells. However, taken alone—meaning specifically without water in it—the vacuole actually collapses (the typical wilting of some plants not watered for some time). Microfilaments don’t provide for support; they aid in movement. Microtubules have a role in support as a cytoskeleton. Rough ER and the nucleus have no rigidity to them. The cell wall is the constant source of rigidity in plant cells.
