A continuous system of air passages from aerial leaves to anchored roots is found in

Options

A. Submerged hydrogphytes
B. Floating hydrophytes
C. Emergent hydrophytes
D. Suspended hydrophytes..

Answer

To solve the question regarding which type of plant has a continuous system of air passages from aerial leaves to anchored roots, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Hydrophytes**:
- **Submerged Hydrophytes**: These plants are completely underwater and do not have access to air directly from the atmosphere.
- **Floating Hydrophytes**: These plants float on the surface of the water but do not have a continuous air passage to their roots since they are partially submerged.
- **Suspended Hydrophytes**: These plants are found just below the water surface, similar to floating hydrophytes, and also lack a continuous air passage system.
- **Emergent Hydrophytes**: These plants grow in water but have parts (like leaves and stems) that extend above the water surface, allowing for direct contact with the air.

2. **Identify the Characteristics of Emergent Hydrophytes**:
- Emergent hydrophytes are adapted to grow in aquatic environments while still being able to access air. Their structure allows for a continuous system of air passages that connect their aerial parts (leaves) to their anchored roots in the water.

3. **Evaluate the Options**:
- Since submerged, floating, and suspended hydrophytes do not have a continuous air passage system, they cannot be the correct answer. The only type that allows for a direct air passage from leaves to roots is emergent hydrophytes.

4. **Conclude the Answer**:
- Therefore, the correct answer to the question is **emergent hydrophytes**.

### Final Answer:
The continuous system of air passages from aerial leaves to anchored roots is found in **emergent hydrophytes**.
