Select the option regarding the tissues that are grouped under the ground tissues?

Options

A. all tissues internal to endodermis
B. all tissues external to endodermis
C. all tissues external epidermis and vascular bundles
D. epidermis and cortex

Answer

To answer the question regarding the tissues that are grouped under ground tissues, we need to understand what ground tissues are and their components.

### Step-by-Step Solution:

1. **Understanding Ground Tissues**: Ground tissues are the tissues in plants that are neither epidermis (outer covering) nor vascular tissues (xylem and phloem). They serve various functions including storage, photosynthesis, and support.

2. **Identifying Components of Ground Tissues**: The main types of tissues that fall under ground tissues include:
- **Parenchyma**: These are living cells that are involved in storage, photosynthesis, and tissue repair.
- **Collenchyma**: These provide support and flexibility to the plant, especially in young stems and leaves.
- **Sclerenchyma**: These are thick-walled cells that provide rigidity and strength to the plant.

3. **Excluding Other Tissues**: As per the definition, we exclude epidermis and vascular tissues (xylem and phloem) from the ground tissue category.

4. **Ground Tissue in Different Plant Parts**:
- In stems and roots, ground tissues include cortex, pith, and other simple tissues like parenchyma, collenchyma, and sclerenchyma.
- In leaves, the ground tissue is referred to as mesophyll, which is primarily made up of chlorenchyma (a type of parenchyma containing chloroplasts).

5. **Conclusion**: Therefore, the correct answer will be the tissues that are not epidermis or vascular tissues, which include parenchyma, collenchyma, sclerenchyma, cortex, pith, and mesophyll.
