Options

A. Glomus
B. Agaricus
C. Rhizobium
D. Nostoc

Answer

**Step-by-Step Solution:**

1. **Understanding Mycorrhizae**: Mycorrhizae are symbiotic associations between fungi and plant roots. They play a crucial role in enhancing nutrient and water absorption for plants.

2. **Types of Mycorrhizae**: There are two main types of mycorrhizae:
- **Ectomycorrhizae**: These fungi form a sheath around the roots and do not penetrate the root cells.
- **Endomycorrhizae**: These fungi penetrate the root cells and form structures like arbuscules and vesicles inside the plant roots.

3. **Identifying the Genus**: The question specifically asks for the genus associated with endomycorrhizae. The most well-known genus that forms endomycorrhizae is **Glomus**.

4. **Evaluating Other Options**: The question may provide other options to choose from. In this case:
- **Agaricus**: A genus of mushrooms, not associated with mycorrhizae.
- **Rhizobium**: A genus of nitrogen-fixing bacteria, not related to mycorrhizae.
- **Nostoc**: A genus of free-living cyanobacteria, also not related to mycorrhizae.

5. **Conclusion**: Based on the information, the correct answer to the question is that endomycorrhiza belongs to the genus **Glomus**.

**Final Answer**: Endomycorrhiza belongs to the genus **Glomus**.
