What is transpiration ?

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Transpiration**: Transpiration is a biological process where plants lose water, primarily in the form of vapor.

2. **Mechanism of Water Loss**: This loss of water occurs through small openings on the leaves called stomata. Stomata are tiny pores that regulate gas exchange and water loss in plants.

3. **Water Absorption**: The process begins with the absorption of water from the soil by the plant roots. The roots take up water through osmosis, which is then transported throughout the plant.
