Mitrospores of algae differentiate through

Options

A. Meiosis
B. Mitosis
C. Fusion of gametes
D. Fragmentation.

Answer

**Step-by-Step Solution:**

1. **Understanding Algae Reproduction**: Algae primarily reproduce through both asexual and sexual methods. Asexual reproduction often involves the formation of zoospores, while sexual reproduction leads to the formation of gametes.

2. **Life Cycle of Algae**: Algae typically exhibit a haplontic life cycle, meaning they spend most of their life in the haploid (N) gametophyte stage. The zygote formed after fertilization is diploid (2N) and develops into a sporophyte.

3. **Formation of Spores**: In the sporophyte stage, the diploid zygote undergoes meiosis to produce haploid spores. However, in many algae, the spores are formed through mitosis rather than meiosis.

4. **Differentiation of Microspores**: Microspores, which are a type of spore, differentiate through mitosis. This process occurs after the formation of the sporophyte, where mitotic divisions lead to the production of microspores.

5. **Eliminating Other Options**:
- **Neiosis**: This is not the correct answer as meiosis is not the primary method for microspore formation in algae.
- **Fusion of Gametes**: This refers to fertilization, which does not directly lead to the differentiation of microspores.
- **Fragmentation**: This is a method of asexual reproduction and does not pertain to the differentiation of microspores.

6. **Conclusion**: Based on the understanding of the life cycle and reproduction methods in algae, the correct answer is that microspores of algae differentiate through **mitosis**.

**Final Answer**: The microspores of algae differentiate through **mitosis** (Option B).
