Phenomenon not associated with root pressure is

Options

A. Sap exudation
B. Bleeding
C. guttation
D. Transpiration

Answer

**Step-by-Step Solution:**

1. **Understanding Root Pressure**: Root pressure is the pressure exerted in the roots of plants that helps in the upward movement of water and nutrients through the xylem. It is primarily caused by the osmotic pressure generated when water is absorbed from the soil.

2. **Analyzing the Options**:
- **Option A: Sap Exudation**: This refers to the leakage of sap from the plant, which can occur due to root pressure pushing the sap upwards. Therefore, sap exudation is associated with root pressure.
- **Option B: Bleeding**: In plants, bleeding refers to the discharge of a watery solution from a cut or damaged part of the plant. This process does not involve root pressure; instead, it occurs due to injury to the plant.
- **Option C: Guttation**: Guttation is the process of water loss in the form of droplets from the edges of leaves, which is facilitated by root pressure.
- **Option D: Transpiration**: Transpiration is the loss of water vapor from the aerial parts of the plant, which is also influenced by root pressure.

3. **Identifying the Correct Answer**: Among the options analyzed, bleeding is the only phenomenon that is not associated with root pressure. Therefore, the correct answer is **bleeding**.

**Final Answer**: The phenomenon not associated with root pressure is **bleeding**.
