The transport of sap from root to top of the plant is

Options

A. Ascent of sap
B. Conduction
C. Transport
D. Translocation

Answer

To solve the question "The transport of sap from root to top of the plant is," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking about the process by which sap (which includes water and nutrients) moves from the roots of a plant to its upper parts.

2. **Identify the Options**: The options provided are:
- Ascent of sap
- Conduction
- Transport
- Translocation

3. **Define Each Term**:
- **Ascent of Sap**: This refers specifically to the upward movement of sap (water and dissolved minerals) from the roots to the leaves.
- **Conduction**: This generally refers to the process of transferring substances through a medium but is not specific to the upward movement in plants.
- **Transport**: This is a broad term that can refer to the movement of substances in any direction within the plant.
- **Translocation**: This usually refers to the movement of organic nutrients (like sugars) throughout the plant, which can occur in various directions.

4. **Focus on the Correct Process**: The upward movement of water and minerals from the roots to the top of the plant is specifically termed the "ascent of sap." This process is primarily driven by transpiration pull, where water evaporates from the leaves, creating a negative pressure that pulls water upward through the xylem.

5. **Conclude the Answer**: Based on the definitions and the specific nature of the process described, the correct answer to the question is **ascent of sap**.

### Final Answer:
The transport of sap from root to top of the plant is known as **ascent of sap**.
