Which of the following method is adopted by the plant for the absorption of water when a cut shoot is fitted in a photometer

Options

A. Active
B. Passive
C. Partly both
D. None of these

Explanation

To solve the question regarding the method adopted by plants for the absorption of water when a cut shoot is fitted in a photometer, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**:
- A photometer is a device used to measure the intensity of light or electromagnetic radiation. In the context of plants, it is often used to study the rate of transpiration.

2. **Identify the Scenario**:
- The question specifically mentions a "cut shoot." This indicates that we are dealing with a part of the plant that has been severed from its root system.

3. **Consider Water Absorption Mechanisms**:
- Plants absorb water primarily through their roots. However, when a shoot is cut, it can no longer absorb water through roots. Instead, water absorption in this scenario relies on other mechanisms.

4. **Focus on Passive Water Absorption**:
- When a cut shoot is placed in a photometer, the primary method of water absorption is through passive means. This involves the process of transpiration, where water evaporates from the surface of the leaves, creating a negative pressure that pulls water upward from the cut end of the shoot.

5. **Evaluate the Options**:
- Given the context of the question, we need to determine which method (from the options provided) corresponds to passive absorption. The correct choice is typically the one that describes transpiration-driven water movement.

6. **Select the Correct Answer**:
- Based on the analysis, the correct answer is **Option B**, which represents the passive method of water absorption through transpiration.

### Final Answer:
- The method adopted by the plant for the absorption of water when a cut shoot is fitted in a photometer is **Option B** (passive absorption through transpiration).
