Why land plants require huge quantity of water for proper growth and development ?

Explanation

### Step-by-Step Text Solution:

1. **Understanding Water Requirement**: Land plants require a significant amount of water for their growth and development. This is primarily due to their physiological processes.

2. **Transpiration Process**: A major reason for the high water requirement in plants is transpiration. Transpiration is the process through which water is absorbed by the roots from the soil, moves through the plant, and is then released as water vapor through small openings in the leaves called stomata.

3. **Water Loss through Transpiration**: It is estimated that plants lose about 90% of the water they absorb through transpiration. This substantial loss necessitates the uptake of large quantities of water to maintain hydration and support various physiological functions.
