Question

Choose the correct answers from the alternatives given.
Osmosis involves the physiological processes that

• A. Maintain shape of the plant
• B. Maintain growth of young cells
• C. Maintain turgor of guard cells
• D. All of these

Answer 1

The correct option is D All of these

Osmosis is a special type of diffusion of water. It is the passage of solvent molecules from a region of their higher concentration to a region of their lower concentration through a semi-permeable membrane.

It maintains the shape of the plant through the osmotic pressure developed in each cell. Since the passage of minerals of takes place through osmosis it also helps in plant growth. During endosmosis, turgor pressure is developed that causes the rigidity of the cells.

Hence, the correct answer is 'All of these'.
