The zygospore of Chlamydomonas gives rise to

Options

A. Zoospore
B. Aplanospore
C. Hypnospore
D. Parthenospore

Answer

**Step-by-Step Solution:**

1. **Understanding Zygospore Formation**: The zygospore is a thick-walled resting cell formed by the fusion of two gametes in Chlamydomonas during sexual reproduction.

2. **Conditions for Development**: The zygospore remains dormant until favorable environmental conditions arise, such as suitable temperature, light, and nutrients.

3. **Germination of Zygospore**: When conditions become favorable, the zygospore undergoes germination. This process involves the zygospore breaking down its thick wall and developing into a new structure.

4. **Formation of Zoospores**: During germination, the zygospore gives rise to zoospores. These are motile spores that are capable of swimming due to the presence of flagella.

5. **Development of New Chlamydomonas**: The zoospores, once released into the environment, can swim and eventually settle down to develop into new Chlamydomonas cells, completing the life cycle.

6. **Conclusion**: Therefore, the zygospore of Chlamydomonas gives rise to zoospores, which lead to the formation of new Chlamydomonas organisms.

**Final Answer**: The zygospore of Chlamydomonas gives rise to zoospores.
