In endomycorrhiza, the fungus is commonly

Options

A. Zygomycete
B. Phycomycete
C. Ascomycete
D. Basidiomycete

Answer

**Step-by-Step Solution:**

1. **Understanding Endomycorrhiza:**
- Endomycorrhiza refers to a type of mycorrhizal association where the fungus penetrates the root cells of the plant. This symbiotic relationship enhances nutrient uptake for the plant and provides carbohydrates for the fungus.

2. **Identifying the Types of Fungi:**
- The question provides four options: eichomorhizae, phycomorhizae, eschomorhizae, and basidiomorhizae. We need to determine which of these is commonly associated with endomycorrhiza.

3. **Analyzing the Options:**
- **Eichomorhizae**: This term does not correspond to a known group of fungi.
- **Phycomorhizae**: This refers to fungi that are saprophytic, meaning they feed on dead organic matter, and are not typically associated with endomycorrhizal relationships.
- **Eschomorhizae**: This term also does not correspond to a recognized fungal group.
- **Basidiomorhizae**: Basidiomycetes are generally associated with ectomycorrhizal relationships and are found on dead organic matter.

4. **Correct Identification:**
- The commonly found fungus in endomycorrhiza is from the group of Zygomycetes, which are also known as pin molds. They are characterized by their ability to penetrate plant roots and establish a symbiotic relationship.

5. **Conclusion:**
- Therefore, the correct answer to the question is Zygomycetes.

**Final Answer:**
- In endomycorrhiza, the fungus is commonly Zygomycetes.
