Cell wall of Chlamydomonas possesses

Options

A. Cellulose
B. Glycoproteins
C. Hemicellulose
D. Proteins only.

Answer

**Step-by-Step Solution:**

1. **Understanding Chlamydomonas**: Chlamydomonas is a unicellular green alga. Knowing its classification helps us understand its cellular structure, including the composition of its cell wall.

2. **Analyzing the Options**:
- **Option A: Cellulose**: Cellulose is a common component of plant cell walls. However, it is not found in the cell wall of Chlamydomonas. Therefore, this option is incorrect.

- **Option B: Glycoproteins**: The cell wall of Chlamydomonas is primarily composed of glycoproteins. Glycoproteins are also found in the extracellular matrix of multicellular green algae and other organisms. This option is correct.

- **Option C: Hemicellulose**: Hemicellulose is another polysaccharide found in plant cell walls, but it is not a component of Chlamydomonas's cell wall. Thus, this option is incorrect.

- **Option D: Proteins only**: While proteins are present in small amounts in various cell walls, they are not the major component of the cell wall in Chlamydomonas. Therefore, this option is also incorrect.

3. **Conclusion**: After evaluating all options, the correct answer is that the cell wall of Chlamydomonas possesses glycoproteins.

**Final Answer**: The cell wall of Chlamydomonas possesses glycoproteins.
