In Pencilium, the asexual reproduction takes place by

Options

A. ascospores
B. aplanospores
C. sporangiospores
D. conidiospores.

Explanation

To answer the question "In Penicillium, the asexual reproduction takes place by," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Organism**: Recognize that Penicillium is a genus of fungi known for its role in the production of antibiotics, particularly penicillin.

2. **Identify Reproductive Methods**: Fungi can reproduce both sexually and asexually. Asexual reproduction in fungi often involves the production of spores.

3. **Examine the Options**: The options given are:
- Ascospores
- Aplanospores
- Sporangiospores
- Conidiospores

4. **Define Each Term**:
- **Ascospores**: Spores produced in a sac-like structure called an ascus, typically associated with sexual reproduction.
- **Aplanospores**: Non-motile spores that can be produced by some algae and fungi.
- **Sporangiospores**: Spores produced within a sporangium, usually associated with asexual reproduction.
- **Conidiospores**: A type of asexual spore that is formed on specialized structures called conidiophores.

5. **Determine the Correct Answer**: In Penicillium, the primary method of asexual reproduction is through the formation of conidiospores. These spores are unicellular, uninucleate, and non-motile, and they are produced on conidiophores.

6. **Conclude**: Therefore, the correct answer is **Conidiospores**.

### Final Answer:
In Penicillium, asexual reproduction takes place by **conidiospores**.
