Discuss the different environmental and plant factors affecting transpiration.

Explanation

### Step-by-Step Text Solution

**1. Understanding Transpiration:**
- Transpiration is the physiological process in plants where water is lost in the form of water vapor. This process occurs primarily through specialized pores called stomata, but can also occur through cuticles and lenticels. It typically happens during the daytime and contributes to a cooling effect on the surrounding environment.

**2. Environmental Factors Affecting Transpiration:**
- **Humidity:**
- The amount of water vapor in the air significantly influences transpiration. Higher humidity leads to lower transpiration rates because the gradient between the water vapor pressure inside the leaf and outside is reduced. Conversely, lower humidity increases transpiration rates.
