Protoderm ' and 'procambium' terms were coined for

Options

A. Permanent tissues
B. Meristematic tissues
C. Intercalary tissues
D. Secondary tissues

Answer

To answer the question regarding the terms "protoderm" and "procambium," we need to understand what these terms refer to in the context of plant anatomy.

### Step-by-Step Solution:

1. **Understanding Tissues in Plants**:
- Plants are made up of various types of tissues, which can be broadly categorized into two main types: permanent tissues and meristematic tissues.

2. **Defining Permanent Tissues**:
- Permanent tissues are composed of cells that have stopped dividing and are specialized for specific functions. They do not contribute to plant growth as they are fully developed and differentiated.

3. **Defining Meristematic Tissues**:
- Meristematic tissues consist of actively dividing cells. These tissues are responsible for the growth of the plant, as they continuously divide to produce new cells.

4. **Identifying Protoderm and Procambium**:
- Protoderm is a type of primary meristem that gives rise to the epidermis, the outer protective layer of the plant.
- Procambium is another type of primary meristem that differentiates into vascular tissues, specifically xylem and phloem, which are essential for the transport of water, nutrients, and food within the plant.

5. **Conclusion**:
- Since both protoderm and procambium are types of meristematic tissues, the correct answer to the question is that these terms are coined for "meristematic tissue."

### Final Answer:
**Protoderm and procambium are terms coined for meristematic tissue.**
