Which class of tissue seems to tbe the most primitive among all types of tissues?

Options

A. Fibres
B. Vessels
C. Parenchyma
D. Sieve tubes.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which class of tissue is considered the most primitive among all types of tissues in flowering plants.

2. **Identifying the Options**: The options provided are:
- 1. Fibers
- 2. Vessels
- 3. Parenchyma
- 4. Seed

3. **Analyzing Each Option**:
- **Fibers**: These are part of sclerenchyma, which is a type of supportive tissue. Fibers are specialized and not considered primitive.
- **Vessels**: These are part of the xylem and are involved in the transport of water. They are also specialized structures and not primitive.
- **Parenchyma**: This is a simple permanent tissue that is living and performs various functions such as storage and photosynthesis. It has less intercellular space and forms a major part of plant tissues.
- **Seed**: This is not a tissue but a reproductive structure, so it cannot be considered in this context.

4. **Conclusion**: Among the options, parenchyma is the simplest and most primitive type of tissue as it is basic and performs essential functions in plants.

5. **Final Answer**: The correct answer is **3. Parenchyma**.
