Describe three factors responsible for the process of ascent of sap in plants

Explanation

### Step-by-Step Solution:

1. **Understanding Ascent of Sap**: The ascent of sap in plants refers to the upward movement of water and dissolved minerals from the roots to the leaves, primarily occurring through the xylem vessels.

2. **Identifying Key Factors**: There are three main factors responsible for the ascent of sap:
- **Cohesion**: This is the mutual attraction between water molecules. Water molecules tend to stick together due to hydrogen bonding, which creates a continuous column of water in the xylem. This cohesion helps in maintaining the integrity of the water column against the forces of gravity.

- **Adhesion**: This refers to the attraction between water molecules and the polar surfaces of the xylem vessels. The water molecules adhere to the walls of the xylem, which helps to counteract the force of gravity and assists in the upward movement of water.
