The plant body of green algae may be -

Options

A. Unicellular
B. Colonial
C. Filamentous
D. All

Answer

**Step-by-Step Solution:**

1. **Understanding Green Algae**: Green algae are simple organisms that belong to the plant kingdom. They are primarily autotrophic, meaning they can produce their own food through photosynthesis.

2. **Classification of Algae**: Algae are generally divided into three main classes:
- Green Algae (Chlorophyceae)
- Red Algae (Rhodophyceae)
- Brown Algae (Phaeophyceae)

3. **Forms of Green Algae**: Green algae can exist in various forms. The main forms include:
- **Unicellular**: An example is Chlamydomonas, which is a single-celled green algae.
- **Colloidal**: An example is Volvox, which exists in a colloidal form.
- **Filamentous**: An example is Spirogyra, which has a filamentous structure.

4. **Conclusion**: Since green algae can be found in all three forms—unicellular, colloidal, and filamentous—the correct answer to the question is that the plant body of green algae may be all of these forms.

**Final Answer**: The plant body of green algae may be unicellular, colloidal, filamentous, and all of these options are correct.
