Plants lose water by the process of ___________ and ____________ .

Explanation

**Step-by-Step Solution:**

1. **Identify the Processes of Water Loss in Plants:**
- Plants lose water primarily through two processes: transpiration and photosynthesis.

2. **Explain Transpiration:**
- Transpiration is the process where water vapor is lost from the aerial parts of the plant, mainly through small openings called stomata. This process is influenced by environmental factors such as temperature and light intensity. When the temperature is high or when there is ample light, the rate of transpiration increases as the plant needs to balance water loss and uptake.
