Question

Why do plant cells possess large sized vacuole?

Answer 1

Hint:Vacuoles are the storage sacs for the solid or liquid contents. Most of a plant cell’s volume depends on the material in vacuole. Vacuole is a membrane- bound sac within the cytoplasm of a cell that functions in several different ways.

Complete step by step answer:The large sizes vacuoles of plant cells maintain the osmotic pressure, turgidity and rigidity of the cell because of the presence of cell sap. Vacuoles are mostly present in plant cells. These are like storage bubbles that occupy the larger portion i.e. ninety percent volume of the plant cell than animal cell. They might store food, water and any variety of nutrients that cell might need to survive. They also store toxic metabolic by-products of plant cells so that the rest of the cell is protected from contamination. The waste products are slowly broken in small pieces that cannot hurt the cell.

Additional information:Actually, when a plant cell has stopped growing, there is usually one very large vacuole that takes up more than half the volume of the cell. Many substances that are important in the life of the plant cell are stored in vacuoles. These include amino acids, sugars, various organic acids and some proteins.

Note:There may be several vacuoles in a single cell. Each vacuole is separated from the cytoplasm by a single unit called tonoplast. A vacuole is used when a large amount of substance is taken in through called endocytosis and when excreted through is called exocytosis.
