In hydrophytes
(a) Root system is well developed
(b) Vascular system is poorly developed
(c) Root system is poorly developed
(d) Vascular system is poorly developed.

Options

A. Root system is well develped
B. Vascular system is poorly developed
C. Root system is poorly developed
D. Vascular system is poorly developed.

Answer

To solve the question about the characteristics of hydrophytes, we need to analyze each option provided:

1. **Understanding Hydrophytes**:
- Hydrophytes are plants that live in water. They are adapted to aquatic environments and have specific features that differentiate them from terrestrial plants.

2. **Analyzing the Options**:
- **Option (a)**: Root system is well developed.
- This option is incorrect. Hydrophytes do not require a well-developed root system because they are surrounded by water, which provides them with the necessary moisture.

- **Option (b)**: Vascular system is poorly developed.
- This option is also incorrect. Hydrophytes typically have a well-developed vascular system to transport nutrients and water effectively, similar to terrestrial plants, although their needs may differ.

- **Option (c)**: Root system is poorly developed.
- This option is correct. Since hydrophytes are submerged in water, their roots do not need to be well-developed for water absorption, leading to a poorly developed root system.

- **Option (d)**: Vascular system is poorly developed.
- This option is incorrect. Hydrophytes have a vascular system that is generally well-developed to facilitate the transport of nutrients and water.

3. **Conclusion**:
- The correct answer is **(c) Root system is poorly developed**. This is due to the fact that hydrophytes absorb water directly from their environment rather than relying solely on their roots.
