Which one lacks both roots and stomata

Options

A. Hydrophytes
B. Mesophytes
C. Hygrophytes
D. Halophytes.

Answer

To determine which type of plant lacks both roots and stomata, we need to analyze the characteristics of the given options: Hydrophytes, Mesophytes, Hygrophytes, and Halophytes.

### Step-by-Step Solution:

1. **Understanding Hydrophytes**:
- Hydrophytes are plants that grow in water. They are adapted to aquatic environments.
- Some hydrophytes have poorly developed roots or may lack roots entirely.
- Additionally, some hydrophytes can have stomata, while others do not.

2. **Analyzing Mesophytes**:
- Mesophytes are plants that grow in environments with a moderate amount of water.
- They typically have well-developed roots and stomata to facilitate water absorption and gas exchange.

3. **Examining Hygrophytes**:
- Hygrophytes are plants that thrive in very moist or wet conditions.
- These plants usually have well-developed roots and stomata for efficient water uptake and gas exchange.

4. **Looking at Halophytes**:
- Halophytes are plants that grow in saline (salty) environments.
- They have adaptations to deal with high salt concentrations, including well-developed roots and stomata.

5. **Conclusion**:
- Among the options, Hydrophytes are the ones that can lack both roots and stomata.
- Therefore, the correct answer is **Hydrophytes**.

### Final Answer:
The plant type that lacks both roots and stomata is **Hydrophytes**.
