Fungal hyphae remian intercellular in

Options

A. Endomycorrhiza
B. VAM
C. Ectomycorrhiza
D. Both B and C.

Answer

To solve the question "Fungal hyphae remain intercellular in," we need to understand the types of mycorrhizal associations that fungi can form with plants. Here's a step-by-step breakdown of the solution:

### Step-by-Step Solution

1. **Understand Mycorrhizae**: Mycorrhizae are symbiotic associations between fungi and plant roots. They can be classified into two main types: endomycorrhizae and ectomycorrhizae.

2. **Define Endomycorrhizae**: In endomycorrhizae, the fungal hyphae penetrate the cell walls and membranes of the plant cells. This type includes vesicular-arbuscular mycorrhizae (VAM), where the hyphae form structures inside the plant cells.

3. **Define Ectomycorrhizae**: In ectomycorrhizae, the fungal hyphae do not penetrate the plant cells. Instead, they remain in the intercellular spaces, forming a network around the plant roots.

4. **Analyze the Options**: The options given are:
- A) Endomycorrhizae
- B) Ectomycorrhizae
- C) Both B and C
- D) VAM (which is a type of endomycorrhizae)

5. **Determine the Correct Answer**: Since endomycorrhizae (including VAM) involve penetration into the plant cells, they do not fit the criterion of remaining intercellular. Ectomycorrhizae, on the other hand, do remain in the intercellular spaces. Therefore, the correct answer is **B) Ectomycorrhizae**.

### Final Answer
**Fungal hyphae remain intercellular in: Ectomycorrhizae (Option B).**
