Osmosis is of immense importance to plants. Which arc described as below?

i. large quantities of water are absorbed by root and root hairs from soil by osmosis.

ii. The movement and distribution of water across the cells of the plant takes place by the process of osmosis.

iii. Endosmosis and exosmosis arc responsible for opening and closing of the stomata.

ADVERTISEMENTS:

iv. The form and shape of many cells and the keeping of the plasma membrane near the cell wall are dependent upon osmotic phenomena.

v. High osmotic concentration increases the resistance of plants to freezing temperature and desiccation.

vi. The turgor of guard cells is absolutely essential for opening of stomata.

vii. In lover plants turgor pressure provides mechanical strength.

ADVERTISEMENTS:

viii. Growth of young cells is brought about by the osmotic pressure and turgor pressure of these cells.

ix. Many plant movements involve changes in turgor which are brought about by osmosis.

x. The various cell organ cells such as chloroplasts, mitochondria etc. will collapse if they are not able to maintain a proper osmotic concentration of solutes.
