Question

Vacuoles are membrane-bound organelles found in plant cells and some protist, animal, and bacterial cells.



Which BEST explains how the vacuole functions within the plant cell to maintain homeostasis?



A.
The vacuole is able to absorb and/or release water through turgor pressure and works with the cell wall to maintain the integrity of the cell.

B.
The vacuole is able to absorb and/or release proteins through turgor pressure and works with the cell wall to maintain the integrity of the cell.

C.
The vacuole is able to provide instructions to the cell through turgor pressure and works with the cell wall to maintain the integrity of the cell.

D.
The vacuole is able to break down sunlight that enters the cell through turgor pressure and works with the cell wall to maintain the integrity of the cell.

Answer 1

A

The central vacuole stores water and solutes and regulates osmotic balance. By filling with water it generates turgor pressure that presses the plasma membrane against the cell wall, keeping the cell rigid and helping maintain homeostasis.
