Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When a plant is wilted what organelle helps it survive?
A
vacuole
B
chromosomes
C
mitochondria
D
nuclei
Explanation: 

Detailed explanation-1: -In the absence of enough water, however, central vacuoles shrink and turgor pressure is reduced, compromising the plant’s rigidity so that wilting takes place.

Detailed explanation-2: -Vacuoles are the organelles that prevent the plant from wilting. The central vacuole refers to a cellular organelle found in plant cells. It is usually the biggest organelle in the cell. It functions to maintain the adequate pressure inside the cells of the plant to offer support and structure for the developing plant.

Detailed explanation-3: -The reduced volume of water in the vacuole reduces the turgor pressure exerted upon the cell membrane, so it pulls away from the cell wall. This causes the cell to reduce in size and appear shrunken and wrinkled.

Detailed explanation-4: -A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
