The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Ground Tissue System**: The ground tissue system in plants is primarily composed of simple and permanent tissues. These tissues are essential for various functions within the plant. 2. **Definition of Simple Tissues**: Simple tissues consist of only one type of cell. This uniformity in cell type means that the functions of these tissues are also similar. 3. **Definition of Permanent Tissues**: Permanent tissues are made up of non-dividing cells. Unlike meristematic tissues, which are capable of continuous division, permanent tissues have completed their growth and differentiation. 4. **Types of Cells in Ground Tissue**: The ground tissue system includes three main types of cells: - **Parenchyma Cells**: These cells are involved in storage, photosynthesis, and tissue repair. They are typically living cells with thin cell walls. - **Collenchyma Cells**: These provide support and flexibility to the plant. They have thicker cell walls and are often found in young stems and leaves. - **Sclerenchyma Cells**: These cells provide structural support due to their thick, lignified walls. They are usually dead at maturity. 5. **Functions of Ground Tissue**: The ground tissue system serves several functions: - It fills the interior of the plant, providing a medium for metabolic processes. - It offers mechanical support to the plant structure. - It is involved in the storage of food and water. 6. **Conclusion**: Therefore, the ground tissue system consists of parenchyma, collenchyma, and sclerenchyma cells. The correct answer to the question is option number 4: all of the above. ---
