Protoderm and Procambium are

Options

A. permanent tissues
B. meristematic tissues
C. intercalary tissues
D. secondary tissues

Answer

**Step-by-Step Solution:**

1. **Definition of Protoderm**: Protoderm is the outermost layer of meristematic tissue found in the embryos and growing regions of plants, particularly in stems and roots. It is responsible for giving rise to the epidermis, which serves as a protective outer layer for the plant.

2. **Definition of Procambium**: Procambium is a type of meristematic tissue that is formed by the apical meristem in the roots and shoots of plants. It plays a crucial role in the development of vascular tissues, which are essential for the transport of water, minerals, and nutrients throughout the plant.

3. **Understanding Vascular Tissues**: Vascular tissues include xylem and phloem. Xylem is responsible for conducting water and minerals from the roots to other parts of the plant, while phloem transports food materials produced during photosynthesis to various parts of the plant.

4. **Classification of Tissues**:
- **Permanent Tissues**: These are mature tissues that have lost the ability to divide. They perform specific functions and do not undergo further division.
- **Meristematic Tissues**: These are tissues that retain the ability to divide throughout the life of the plant. They are responsible for growth and development.
- **Intercalary Tissues**: These are found at the internodes of stems and help in increasing the length of the plant.
- **Secondary Tissues**: These are formed from permanent tissues and contribute to the secondary growth, which increases the girth of the plant.

5. **Conclusion**: Both protoderm and procambium are classified as meristematic tissues because they are actively dividing and contribute to the formation of the epidermis and vascular tissues, respectively.
