Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Choose the correct property for the vacuole of a plant cell.
A
Thick layer around the cell
B
Contains large amount of water
C
Contains non green pigments
D
Contains green pigments
Explanation: 

Detailed explanation-1: -A vacuole is a membrane bound structure found in the cytoplasmic matrix of a cell. The membrane surrounding the vacuole is known as tonoplast.

Detailed explanation-2: -Within plant cells, there is a large vacuole called the central vacuole. A cell’s vacuole is a spherical filled with liquid and molecules. In a plant cell, the central vacuole stores water and regulates turgor pressure.

Detailed explanation-3: -Plant cells additionally possess large, fluid-filled vesicles called vacuoles within their cytoplasm. Vacuoles typically compose about 30 percent of a cell’s volume, but they can fill as much as 90 percent of the intracellular space.

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.

Detailed explanation-5: -As water enters the cell, the contractile vacuole expands. Then when there is too much water in the cell, the contractile vacuole contracts, expelling excess water along with waste products and pushing them out of the cell.
