Simple permanent tissue that performs various functions like - photosynthesis, storage, secretion etc., is -

Options

A. Parenchyma
B. Collenchyma
C. Sclerenchyma
D. xylem

Answer

To solve the question regarding the simple permanent tissue that performs various functions like photosynthesis, storage, secretion, etc., we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Types of Tissues**: Understand that plant tissues are categorized into two main types: meristematic and permanent tissues. Permanent tissues can be further divided into simple and complex tissues.

2. **Define Simple Permanent Tissues**: Simple permanent tissues consist of one type of cell and include parenchyma, collenchyma, and sclerenchyma.

3. **Analyze the Functions of Each Tissue**:
- **Parenchyma**: These are living cells that perform various functions such as photosynthesis (due to the presence of chlorophyll), storage of food and water, and secretion of substances.
- **Collenchyma**: Primarily provides support and flexibility to young stems and leaves, but does not perform photosynthesis or storage.
- **Sclerenchyma**: Composed of dead cells that provide structural support; they do not perform photosynthesis or storage.
- **Xylem**: A complex tissue responsible for the transport of water and minerals; it does not perform photosynthesis or storage.

4. **Determine the Correct Answer**: Based on the functions outlined, parenchyma is the only tissue that performs photosynthesis, storage, and secretion.

5. **Conclusion**: Therefore, the answer to the question is **A. Parenchyma**.
