What is bleeding in plants?

Explanation

**Step-by-Step Solution:**

1. **Definition of Bleeding in Plants**: Bleeding in plants refers to the process where sap leaks out from the plant tissues, particularly when the plant is injured or cut.

2. **Cause of Bleeding**: This phenomenon occurs due to the internal pressure of the sap within the plant tissues. The sap is a mixture of water, nutrients, and sugars that the plant transports through its vascular system.

3. **Involved Tissues**: The primary tissue responsible for the conduction of water in plants is the xylem. The xylem transports water and dissolved minerals from the roots to the rest of the plant.
