Opening of floral bud is an example of
(a) Induced movement
(b) Hyponastic movement
(c) Epinastic movement
(d) Cleistogamous movement

Options

A. Induced movement
B. Hyponastic movement
C. Epinastic movement
D. Cleistogamous movement

Answer

To determine the correct answer to the question regarding the opening of a floral bud, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Movements**:
- We need to differentiate between the types of movements mentioned in the options: induced movement, hyponastic movement, epinastic movement, and cleistogamous movement.

2. **Define Epinastic Movement**:
- Epinastic movement refers to the growth of plant parts in such a way that the upper parts grow faster than the lower parts. This can lead to the bending or opening of structures like floral buds.

3. **Analyze the Floral Bud Opening**:
- The opening of a floral bud is primarily due to the growth of the upper parts of the bud, which is characteristic of epinastic movement.

4. **Eliminate Incorrect Options**:
- **Induced Movement**: This refers to movements that occur in response to external stimuli, which does not apply to the autonomous opening of a floral bud.
- **Hyponastic Movement**: This is the opposite of epinastic movement, where the lower part grows faster than the upper part, causing upward bending. This does not describe the opening of a floral bud.
- **Cleistogamous Movement**: This refers to a type of flowering where flowers self-pollinate without opening. This is not relevant to the opening of floral buds.

5. **Conclude with the Correct Answer**:
- Since the opening of a floral bud is due to the faster growth of the upper parts, it is classified as an **epinastic movement**. Therefore, the correct answer is **(c) Epinastic movement**.

### Final Answer:
(c) Epinastic movement
