After fertilisation,Tegmen of the seed develops from

Options

A. Perisperm
B. Funiculus
C. Inner integument
D. Outer Integument

Answer

**Step-by-Step Solution:**

1. **Understanding Seed Structure**: Begin by recognizing the structure of a seed. A seed consists of several parts, including the seed coat, which is made up of layers derived from the ovule.

2. **Identifying Seed Coats**: The seed coat is composed of two layers: the outer layer known as the testa and the inner layer known as the tegmen.

3. **Role of Integuments**: The seed coats develop from the integuments of the ovule. The ovule has two integuments: an outer integument and an inner integument.

4. **Post-Fertilization Changes**: After fertilization, the ovule transforms into a seed. During this transformation, the integuments develop into the seed coats.

5. **Determining the Source of Tegmen**: The outer integument forms the testa, while the inner integument develops into the tegmen.

6. **Conclusion**: Therefore, the tegmen of the seed develops from the inner integument of the ovule.

**Final Answer**: The tegmen of the seed develops from the inner integument of the ovule.
