Which of the following processes will be affected due to water scarcity on plants ?

Options

A. Evaporation,A and B
B. Photosynthesis,B and C
C. Respiration,A and C
D. Transpiration,B and D

Answer

To determine which processes will be affected due to water scarcity on plants, we can analyze the following steps:

### Step 1: Understand the Processes
Identify the processes that are essential for plant growth and survival. The primary processes to consider are:
- Evaporation
- Photosynthesis
- Respiration
- Transpiration

### Step 2: Analyze Each Process
1. **Evaporation**: This process typically refers to water turning into vapor from bodies of water, not directly from plants. Therefore, while plants do lose water, this is more related to transpiration.

2. **Photosynthesis**: This is the process by which plants use sunlight, carbon dioxide, and water to produce glucose (food) and oxygen. Water is a crucial component of this process. If there is water scarcity, photosynthesis will be significantly affected as plants cannot produce food efficiently.

3. **Respiration**: This process involves plants taking in oxygen and releasing carbon dioxide. Water is not directly involved in this process, so it will not be significantly affected by water scarcity.

4. **Transpiration**: This is the process where water evaporates from the leaves of plants into the atmosphere. Water scarcity will greatly affect transpiration because there will be less water available for the plants to lose through their leaves.

### Step 3: Conclusion
Based on the analysis:
- Photosynthesis and transpiration are the two processes that will be affected due to water scarcity on plants.

Therefore, the correct answer is that both photosynthesis and transpiration will be affected due to water scarcity.

### Final Answer
The processes that will be affected due to water scarcity on plants are **photosynthesis and transpiration**.
