Presence of thin and small roots is the characteristic feature of which group of plants?

Options

A. Mesophytes
B. Xerophyte
C. Hydrophyte
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Plant Groups**: Begin by identifying the different groups of plants based on their habitat and adaptations. The main groups include mesophytes, xerophytes, and hydrophytes.

2. **Defining Mesophytes**: Mesophytes are terrestrial plants that thrive in moderate conditions. They have well-developed root systems that can penetrate deep into the soil to access water.

3. **Defining Xerophytes**: Xerophytes are adapted to survive in arid environments, such as deserts. They have deep roots to search for water, which helps them endure harsh climatic conditions.

4. **Defining Hydrophytes**: Hydrophytes are plants that grow in water or in very moist environments. They have adapted to their watery habitat, resulting in thin and small roots. This adaptation is because their roots do not need to reach deep into the soil for water, as it is readily available at the surface.

5. **Conclusion**: Based on the characteristics of each group, the presence of thin and small roots is a defining feature of hydrophytes. These plants do not require extensive root systems since they absorb water directly from their aquatic environment.

**Final Answer**: The presence of thin and small roots is a characteristic feature of hydrophytes.
