Name the following:
(i) Tissue through which ascent of sap occurs.
(ii) Universal solvent.

Explanation

### Step-by-Step Solution:

1. **Identify the Tissue for Ascent of Sap**:
- The ascent of sap refers to the upward movement of water and dissolved minerals from the roots to the leaves of a plant. This process is primarily facilitated by a specific type of tissue.
- The tissue responsible for this upward movement is **xylem**. Xylem contains specialized cells, such as tracheids and vessel elements, that aid in the transport of water.

2. **Understand the Concept of Universal Solvent**:
- A universal solvent is a substance that can dissolve most chemical substances. In biological systems, this property is crucial for various physiological processes.
