Which one of the following acts as water storage tissue in succulent plants ?
(a) Parenchyma
(b) Aerenchyma
(c) Angular collenchyma
(d) Meristem

Options

A. Parenchyma
B. Aerenchyma
C. Angular colenchyma
D. Meristem

Answer

To solve the question "Which one of the following acts as water storage tissue in succulent plants?", we need to analyze the options provided:

1. **Understanding the question**: The question asks for the type of tissue that functions primarily in water storage in succulent plants.

2. **Reviewing the options**:
- (a) Parenchyma
- (b) Aerenchyma
- (c) Angular collenchyma
- (d) Meristem

3. **Analyzing each option**:
- **Parenchyma**: This is a type of plant tissue that is generally involved in storage, photosynthesis, and tissue repair. In succulent plants, parenchyma can be modified to form aquiferous parenchyma, which is specialized for water storage. These cells have thin walls and large vacuoles that can store water.
- **Aerenchyma**: This tissue is characterized by large air spaces and is primarily involved in gas exchange, not water storage.
- **Angular collenchyma**: This type of tissue provides support to the plant and is not involved in water storage.
- **Meristem**: This is a type of tissue responsible for growth and does not function in water storage.

4. **Conclusion**: Based on the analysis, the correct answer is (a) Parenchyma, specifically the modified form known as aquiferous parenchyma, which is adapted for water storage in succulent plants.

**Final Answer**: (a) Parenchyma
