Rhizoids of mosses are

Options

A. Unicellular and pigmented
B. Multicellular and pigmented
C. Unicellular and non-pigmented
D. Multicellular and non-pigmented

Answer

### Step-by-Step Solution:

1. **Understanding Rhizoids**:
- Rhizoids are structures that resemble roots in primitive plants, particularly in mosses, which belong to the group Bryophyta.

2. **Classification of Rhizoids**:
- Rhizoids can be classified based on their cellular structure and pigmentation. The options provided are:
- Unicellular pigmented
- Multicellular pigmented
- Unicellular non-pigmented
- Multicellular non-pigmented

3. **Characteristics of Moss Rhizoids**:
- Moss rhizoids are primarily **multicellular**, meaning they are composed of multiple cells.
- They are also **non-pigmented**, which indicates that they do not contain chlorophyll or other pigments that would give them color.

4. **Conclusion**:
- Based on the characteristics of rhizoids in mosses, the correct answer is that rhizoids of mosses are **multicellular non-pigmented**. Therefore, the correct option is **D**.
