Thread-like fungal structures are

Options

A. Hyphae
B. Mycelium
C. Rhizomorphs
D. Sclerotia

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about thread-like structures found in fungi.

2. **Identifying the Options:**
The options provided are:
- Hyphae
- Mycelium
- Rhizomorphs
- Sclerotia

3. **Analyzing Each Option:**
- **Hyphae:** These are the basic structural units of fungi, consisting of long, thread-like filaments. They are typically tubular and can be single or multi-cellular.
- **Mycelium:** This refers to a network of hyphae. It is not a single thread-like structure but rather a collection of many hyphae.
- **Rhizomorphs:** These are specialized structures that resemble roots and are formed by the aggregation of hyphae. They serve to transport nutrients and water but are not simply thread-like structures.
- **Sclerotia:** These are hardened masses of hyphal threads that serve as a resting structure for some fungi. They are not thread-like in nature.

4. **Conclusion:**
Based on the definitions and characteristics of each option, the correct answer is **hyphae**, as they are the thread-like structures in fungi.

**Final Answer:** Hyphae
