Question

which of the organelles is a membrane-bound sac in the cytoplasm that stores water, food, and waste and helps provide structural support in plant cells?
○ lysosome
○ spindle
○ mitochondrion
○ vacuole
○ centriole

Explanation:

The vacuole is a membrane-bound sac in plant cells that stores water, food, and waste. It also helps maintain turgor pressure, which provides structural support to the cell. Lysosomes digest waste, spindles assist in cell division, mitochondria produce energy, and centrioles organize microtubules—none match the described function.

Answer:

vacuole
