2. **Explain the Function of Zoospores**:
- The primary function of zoospores is to facilitate **asexual reproduction** in algae. They are produced during **unfavorable environmental conditions** and can move to find a more suitable environment. Once conditions improve, zoospores can germinate and develop into new individuals, thus allowing the algae to reproduce without the need for sexual reproduction.
