In Penicillium gamtophytic body develops from

Options

A. Zygospore
B. Ascospore
C. Cleistothecium
D. Parthenospore.

Answer

To answer the question "In Penicillium, the gametophytic body develops from," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Organism**: Recognize that Penicillium is a genus of fungi that reproduces both sexually and asexually.

2. **Identify the Reproductive Structures**: In Penicillium, sexual reproduction occurs through the formation of ascospores. These spores are produced within a specialized structure called an ascus.

3. **Define Gametophytic Body**: The gametophytic body refers to the structure that develops from spores and is involved in the formation of gametes.

4. **Determine the Source of the Gametophytic Body**: In Penicillium, the gametophytic body develops specifically from ascospores, which are the result of sexual reproduction.

5. **Evaluate the Options**:
- **Zygospore**: This is related to Rhizopus, not Penicillium.
- **Ascospore**: This is the correct answer, as it is the spore type produced in Penicillium.
- **Clostrothecium**: This is a closed fruiting body in Ascomycetes, not directly related to the gametophytic body of Penicillium.
- **Parthenospore**: This is a type of resting spore found in certain algae, not relevant to Penicillium.

6. **Select the Correct Option**: Based on the evaluation, the correct answer is **option 2: ascospore**.

### Final Answer:
The gametophytic body in Penicillium develops from **ascospore** (Option 2).
