Out of these 10 organisms, how many organisms belong to the class chlorophyceae, phaeophyceae and rhodophyceae respectively?

Options

A. 4, 3, 3
B. 4, 4, 2
C. 5, 3, 2
D. 6, 2, 2

Answer

To determine how many organisms belong to the classes Chlorophyceae, Phaeophyceae, and Rhodophyceae from the given list of organisms, we can categorize each organism based on their respective classes.

1. **Identify the Organisms**:
- Chlamydomonas
- Chlorella
- Volvox
- Ulothrix
- Fucus
- Dictyota
- Polysiphonia
- Gelidium
- Acetabularia
- Laminaria

2. **Classify Each Organism**:
- **Chlorophyceae (Green Algae)**:
- Chlamydomonas
- Chlorella
- Volvox
- Ulothrix
- Acetabularia
- **Total: 5 organisms**

- **Phaeophyceae (Brown Algae)**:
- Fucus
- Dictyota
- Laminaria
- **Total: 3 organisms**

- **Rhodophyceae (Red Algae)**:
- Polysiphonia
- Gelidium
- **Total: 2 organisms**

3. **Summarize the Results**:
- **Chlorophyceae**: 5 organisms
- **Phaeophyceae**: 3 organisms
- **Rhodophyceae**: 2 organisms

Thus, the final answer is:
- Chlorophyceae: 5
- Phaeophyceae: 3
- Rhodophyceae: 2
