Question

the central vacuole in a plant cell is responsible for turgor pressure. when the vacuole loses water, the cytoplasm shrinks. when the vacuole gains water, the cytoplasm seems to swell up. one structure helps the plant cell keep its shape no matter how much force water is creating in the vacuole. this is the-
a cell wall
b cytoplasm
c cytoskeleton
d cell membrane

Explanation:

The cell wall in plant cells provides structural support and helps maintain the shape of the cell regardless of changes in turgor pressure caused by water - gain or loss in the central vacuole. The cytoplasm, cytoskeleton, and cell membrane do not primarily serve this function of maintaining the overall shape against vacuolar forces.

Answer:

A. cell wall
