Question

Give a long term on Vacuoles ? ( no copy paste )

Answer 1

Answer:

Vacuoles :-

☆ The vacuoles is the membrane-bound space found in the cytoplasm .

• it contains water , sap , excretory products and other materials not useful for the cell .

☆ The vacuole is bound by a single membrane called Tonoplast .

☆ in plant cells , vacuole can occupy upto 90 % of the volume of the cell .

☆ in plants, the Tonoplast facilitates the transport of a number of ions and other materials against concentration gradient into the vacuole.

hence , their concentration is significantly higher in vacuole than in the cytoplasm .

☆ In Amoeba, the contractile vacuole is important for excretion and osmoregulation .

in many cells , as in protists, food vacuoles are formed by engulfing the food particles .

Answer 2

vacuoles - vacuoles are the cell organelle which are found in plant cells and their store the excess material and essential nutrients like minerals waters and its layer is known as tonoplast. in plant cell vacuoles occupy 90% of space. the tonoplast exchange the essential nutrients among the gradient of the vacuole
