Endogenously produced asexual spore in Pythiumis

Options

A. Non-motile and diploid
B. Planospore
C. Thick walled and haploid
D. Meiospore

Answer

To answer the question about the endogenously produced asexual spore in Pythium, we need to analyze the options provided and understand the characteristics of the spores associated with Pythium.

### Step-by-Step Solution:

1. **Identify the Organism**: The question refers to Pythium, which is a genus of water molds known for producing asexual spores.

2. **Understand Asexual Spores**: Asexual spores are produced by organisms to reproduce without the fusion of gametes. In Pythium, the primary type of asexual spores produced is known as zoospores.

3. **Examine the Options**:
- **Non-motile and Diploid Spores**: These are referred to as zoospores. However, the description is incorrect as zoospores are motile.
- **Planospores**: These are motile spores that can swim, and they are indeed produced by Pythium.
- **Thick-walled Encephalopods**: This term does not apply to Pythium; it refers to Chlamydospores found in other organisms.
- **Meospores**: These are sexual spores produced through meiosis, which does not apply to the question about asexual spores in Pythium.

4. **Select the Correct Answer**: Based on the analysis, the correct answer is **Planospores**, as they are the motile asexual spores produced by Pythium.

### Final Answer:
The endogenously produced asexual spore in Pythium is **Planospores**.
