Which is not related to transpiration ?

Options

A. Absorption and distribution of minerals
B. Circulation of water
C. Temperature
D. Bleeding

Answer

**Step-by-Step Solution:**

1. **Understanding Transpiration**: Transpiration is the process by which water vapor is released from the aerial parts of plants, mainly through small openings called stomata. This process is crucial for maintaining water and nutrient flow within the plant.

2. **Analyzing the Options**:
- **Absorption and Distribution of Minerals**: This process is related to transpiration because as water is absorbed by the roots, it also carries minerals and nutrients from the soil to different parts of the plant.
- **Circulation of Water**: This is directly linked to transpiration as the movement of water through the plant is facilitated by the loss of water vapor, creating a negative pressure that pulls water upward from the roots.
- **Temperature**: Transpiration helps in regulating the temperature of the plant. As water evaporates, it cools the plant, which is an important aspect of thermoregulation.
- **Bleeding**: This refers to the exudation of sap from cut or damaged parts of a plant, which is primarily associated with root pressure and guttation, not transpiration.

3. **Identifying the Correct Answer**: Among the options provided, "bleeding" is the process that is not related to transpiration. It is associated with root pressure rather than the evaporation of water.

4. **Conclusion**: Therefore, the correct answer to the question "Which is not related to transpiration?" is **bleeding**.
