VAM represents

Options

A. Saprophytic fungi
B. Symbiotic fungi
C. Saprophytic bacteria
D. Symbiotic bacteria.

Answer

**Step-by-Step Solution:**

1. **Understanding VAM**: VAM stands for Vesicular Arbuscular Mycorrhiza. It is a type of mycorrhizal association that occurs between certain fungi and the roots of plants, specifically angiosperms.

2. **Identifying the Relationship**: VAM represents a symbiotic relationship. In this context, symbiosis refers to the interaction between two different organisms living in close physical proximity, often to the advantage of both.

3. **Role of Fungi**: The fungi involved in VAM belong to the group known as phycomycetes. These fungi help the plant by enhancing its ability to absorb water and nutrients from the soil.

4. **Nutrient Exchange**: In this symbiotic relationship, the fungi receive carbohydrates and other organic compounds from the plant, while the plant benefits from the increased nutrient and water uptake facilitated by the fungi.

5. **Eliminating Incorrect Options**:
- **Separophytic Fungi**: These fungi obtain nutrients from dead and decaying organic matter, which is not the case for VAM.
- **Separophytic Bacteria**: Similar to separophytic fungi, these bacteria also feed on dead organic matter, making this option incorrect.
- **Symbiotic Bacteria**: While this term refers to bacteria that engage in symbiotic relationships, VAM specifically refers to fungi, not bacteria.

6. **Conclusion**: Therefore, the correct answer to what VAM represents is "Symbiotic Fungi."

**Final Answer**: VAM represents Symbiotic Fungi.
