Acetabularia, a largest unicellular plant, belongs to

Options

A. Chlorophyta
B. Rhodophyta
C. Pyrrophyta
D. Phaeophyta

Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question asks about Acetabularia, which is known as the largest unicellular plant.

2. **Understand the Characteristics**: Acetabularia is a unicellular eukaryotic organism. It is notable for its large size and complex structure, which makes it an important model organism for studying cell biology.

3. **Determine the Group**: To classify Acetabularia, we need to look at its characteristics:
- It is unicellular.
- It is photosynthetic and has a green color, indicating the presence of chlorophyll.

4. **Evaluate the Options**: The options provided are:
- Chlorophytum
- Rhodophytum
- Pyrophytum
- Pheophytum

Based on the characteristics of Acetabularia:
- **Chlorophytum**: This group includes green algae, which aligns with Acetabularia's green color and photosynthetic nature.
- **Rhodophytum**: This group consists of red algae, which does not match the characteristics of Acetabularia.
- **Pyrophytum**: This group includes algae that are typically yellow or brown, which again does not match.
- **Pheophytum**: This group consists of brown algae, which is also not applicable.

5. **Conclusion**: Given that Acetabularia is a green unicellular organism, it belongs to the group **Chlorophyta** (green algae).

**Final Answer**: Acetabularia belongs to **Chlorophyta**.
