Dinoflagellates undergo binary fission

Options

A. Longitudinal
B. Transverse
C. Oblique
D. Irregular

Answer

To answer the question regarding the type of binary fission that dinoflagellates undergo, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Dinoflagellates**:
- Dinoflagellates are a group of protists that belong to the Kingdom Protista. They are known for their unique characteristics, including their size, which can range from 5 to 2000 micrometers.

2. **Nutrition in Dinoflagellates**:
- They exhibit a type of nutrition known as myxotrophy, which means they can perform photosynthesis (like plants) as well as heterotrophic nutrition (like animals).

3. **Reproduction in Dinoflagellates**:
- Dinoflagellates primarily reproduce asexually through a process called binary fission. This is a method of reproduction where a single organism divides into two separate organisms.

4. **Types of Binary Fission**:
- Binary fission can occur in various orientations: longitudinal, transverse, oblique, or irregular. Each type refers to the direction in which the organism divides.

5. **Identifying the Correct Type**:
- In the case of dinoflagellates, the binary fission occurs in an oblique manner. This means that the division does not follow a straight line (longitudinal or transverse) but rather at an angle.

6. **Conclusion**:
- Therefore, the correct answer to the question is that dinoflagellates undergo oblique binary fission.

### Final Answer:
Dinoflagellates undergo oblique binary fission.
