What is the common mode of asexual reproduction in chrysophytes?

Options

A. Fragmentation
B. Regeneration
C. Binary fission
D. Sporulation

Answer

To solve the question regarding the common mode of asexual reproduction in chrysophytes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Chrysophytes**:
- Chrysophytes are a group of organisms commonly known as diatoms. They belong to the kingdom Protista.

2. **Understand Asexual Reproduction**:
- Asexual reproduction is a mode of reproduction that does not involve the fusion of gametes. It allows organisms to reproduce without sexual processes.

3. **Analyze the Options**:
- The options provided are:
1. Fragmentation
2. Regeneration
3. Binary fission
4. Sporulation

4. **Determine the Common Mode**:
- Among the options, we need to identify which is the most common mode of asexual reproduction in chrysophytes.
- It is known that chrysophytes primarily reproduce asexually through binary fission, where a single organism divides into two identical daughter cells.

5. **Select the Correct Answer**:
- Based on the understanding that binary fission is the most common method of asexual reproduction in chrysophytes, we conclude that the correct answer is option C: Binary fission.

### Final Answer:
The common mode of asexual reproduction in chrysophytes is **binary fission** (Option C).
