Ground / fundamental tissue system is made up of -

Options

A. Parenchyma
B. Collenchyma
C. Sclerenchyma
D. All

Answer

**Step-by-Step Solution:**

1. **Understanding Ground Tissue System**: The ground or fundamental tissue system is a crucial part of plant anatomy. It serves various functions, including storage, photosynthesis, and support.

2. **Identifying Components**: The ground tissue system is primarily made up of three types of cells:
- **Parenchyma**: These are the most common type of ground tissue cells. They are usually isodimetric (equal in all dimensions) and can have intercellular spaces. Parenchyma cells are involved in functions such as storage, photosynthesis, and tissue repair.
- **Collenchyma**: These cells provide support and flexibility to the plant. They have unevenly thickened cell walls and are usually found in young stems and leaf petioles.
- **Sclerenchyma**: This type of tissue provides strength and support. Sclerenchyma cells have thick, lignified walls and are typically dead at maturity. They include fibers and sclereids.

3. **Conclusion**: Therefore, the ground tissue system is made up of parenchyma, collenchyma, and sclerenchyma cells.

4. **Final Answer**: The ground or fundamental tissue system is made up of all three types of cells: Parenchyma, Collenchyma, and Sclerenchyma.
