What is true about cuticle in plants ?

Options

A. It is always associated with epidermal cells.
B. It is always associated with ground tissue.
C. Cuticle is absent in roots.
D. Both (A) & (C)

Answer

To determine what is true about the cuticle in plants, let's analyze the options provided and understand the characteristics of the cuticle.

### Step-by-Step Solution:

1. **Definition of Cuticle**: The cuticle is a waxy layer that covers the outermost parts of plants, primarily found on the leaves, fruits, flowers, and non-woody stems of higher plants. It serves as a protective barrier.

**Hint**: Remember that the cuticle is primarily a protective layer found on the outer surfaces of plants.

2. **Association with Epidermal Cells**: The cuticle is produced by the epidermal cells of the plant. This means it is always associated with the epidermis, which is the outer layer of cells.

**Hint**: Think about where the cuticle is formed and which cells are responsible for its production.

3. **Association with Ground Tissue**: The cuticle is not associated with ground tissue. Ground tissue is the internal tissue of the plant that is involved in storage, photosynthesis, and support. The cuticle does not play a role in this tissue.

**Hint**: Consider the functions of ground tissue and whether the cuticle serves any of those functions.

4. **Presence in Roots**: The cuticle is typically absent in roots. Roots do not have a cuticle because they are usually in contact with soil moisture and do not require the same level of water retention as leaves do.

**Hint**: Recall the functions of roots and why a protective waxy layer might not be necessary there.

5. **Evaluating the Options**:
- **Option 1**: "It is always associated with epidermal cells." - This is true.
- **Option 2**: "It is always associated with ground tissue." - This is false.
- **Option 3**: "Cuticle is absent in roots." - This is true.
- **Option 4**: "Both A and C." - Since both statements A and C are true, this option is also correct.

### Conclusion:
The correct answer is **Option 4: Both A and C**. The cuticle is always associated with epidermal cells and is absent in roots.
