Ground tissue includes

Options

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

Answer

To answer the question "Ground tissue includes," we need to analyze the options provided and understand the composition of ground tissue in plants.

### Step-by-Step Solution:

1. **Understanding Ground Tissue**: Ground tissue is one of the three main types of plant tissues, alongside dermal and vascular tissues. It plays a crucial role in various plant functions, including photosynthesis, storage, and support.

2. **Identifying Components**: Ground tissue consists of all tissues that are not part of the dermal (epidermis) or vascular (xylem and phloem) systems. This means it includes tissues like parenchyma, collenchyma, and sclerenchyma.

3. **Evaluating the Options**:
- **Option A**: All tissues except epidermis and vascular bundles. This option correctly identifies that ground tissue excludes both dermal and vascular tissues.
- **Option B**: Epidermis and cortex. This option is incorrect because the epidermis is part of the dermal tissue and is not included in ground tissue.
- **Option C**: All tissues internal to endodermis. This is incorrect as it may include vascular tissues.
- **Option D**: All tissues external to endodermis. This option is also incorrect as it may include dermal tissues.

4. **Conclusion**: The correct answer is **Option A**: Ground tissue includes all tissues except epidermis and vascular bundles.

### Final Answer:
Ground tissue includes all tissues except epidermis and vascular bundles.
