Stomata are not found in

Options

A. Algae
B. Mosses
C. Ferns
D. Liverworts

Answer

To solve the question "Stomata are not found in," we will analyze the options provided: algae, mosses, ferns, and liverworts.

### Step-by-Step Solution:

1. **Understanding Stomata**: Stomata are small openings on the surface of leaves that allow for gas exchange. They are primarily found in higher plants and are crucial for photosynthesis and respiration.

2. **Classification of Plants**: Plants are classified into different groups based on their evolutionary history. The major groups relevant to this question are:
- Algae (considered primitive)
- Bryophytes (includes mosses and liverworts)
- Pteridophytes (includes ferns)

3. **Origin of Stomata**: Stomata are believed to have originated after the evolution of bryophytes. This means that any plant group that is more primitive than bryophytes is unlikely to have stomata.

4. **Analyzing the Options**:
- **Algae**: Algae are considered more primitive than bryophytes. Since stomata evolved after bryophytes, algae do not possess stomata.
- **Mosses**: Mosses are bryophytes and do have stomata.
- **Ferns**: Ferns are pteridophytes, which evolved after bryophytes, and they also possess stomata.
- **Liverworts**: Liverworts are also bryophytes and have stomata, although they may be less developed compared to those in higher plants.

5. **Conclusion**: Since stomata are not found in algae, the correct answer to the question is **algae**.

### Final Answer:
Stomata are not found in **algae**.
