Options

A. Sclereids
B. Trichomes
C. Fibres
D. All of the above

Answer

To answer the question regarding what seed coats of legumes and leaves of tea contain, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Seed Coats of Legumes**:
- Seed coats are the outer protective layers of seeds. In legumes, these coats serve to protect the seed from physical damage and desiccation.

2. **Identifying Components of Seed Coats**:
- The seed coats of legumes are primarily composed of **sclerenchyma cells**, which are known for their thick, lignified walls. This structure provides strength and rigidity.

3. **Understanding Leaves of Tea**:
- Tea leaves also have protective structures. The leaves contain various types of cells, including those that provide protection and support.

4. **Identifying Components of Tea Leaves**:
- Similar to seed coats, tea leaves contain **sclerenchyma cells** (specifically, structures called sclerites) that contribute to the leaf's structural integrity and protection.

5. **Conclusion**:
- Both the seed coats of legumes and the leaves of tea contain **sclerenchyma cells**, specifically in the form of sclerites, which are important for protection.

### Final Answer:
The seed coats of legumes and leaves of tea contain **sclerites**.
