Unicisternal dictyosomes are found in

Options

A. plant cells
B. fungi
C. bacteria
D. algal cell

Answer

### Step-by-Step Solution:

1. **Understanding Dictyosomes**:
- Dictyosomes are membrane-bound structures found in cells, resembling a stack of flattened sacs. They play a crucial role in processing and packaging proteins and lipids.

2. **Defining Unicisternal Dictyosomes**:
- Unicisternal Dictyosomes are a type of Dictyosome that contains only a single cistern (the flattened sac). This is important to identify which organisms possess this structure.

3. **Analyzing the Options**:
- **Option 1: Plant Cells**:
- Plant cells typically have multiple cisternae in their Dictyosomes, thus they cannot be classified as unicisternal. This option is incorrect.

- **Option 2: Fungi**:
- Fungi are known to have unicisternal Dictyosomes, which means they contain a single cistern. This option is correct.

- **Option 3: Bacteria**:
- Bacteria do not have Dictyosomes at all, making this option incorrect.

- **Option 4: Algal Cells**:
- Algal cells also do not possess Dictyosomes, so this option is incorrect as well.

4. **Conclusion**:
- After analyzing all the options, the only organism that has unicisternal Dictyosomes is fungi. Therefore, the correct answer is option number 2 (Fungi).
