After fertilization the outer integument of ovule changes into -

Options

A. Testa
B. Tegmen
C. Fruit
D. Seed

Answer

**Step-by-Step Solution:**

1. **Understanding the Ovule Structure**: The ovule is a structure found in the ovary of flowering plants and consists of several parts, including the integuments. The integuments are protective layers surrounding the ovule.

2. **Fertilization Process**: After fertilization occurs, the ovule undergoes significant changes. The fertilization process leads to the formation of a zygote, which eventually develops into a seed.

3. **Development of Seed Coats**: The ovule transforms into a seed, and during this transformation, the integuments of the ovule develop into seed coats. There are two integuments: the outer integument and the inner integument.

4. **Identification of Seed Coats**: The outer integument of the ovule develops into the outer seed coat, known as the testa. The inner integument develops into the inner seed coat, referred to as the tegmen.

5. **Conclusion**: Therefore, after fertilization, the outer integument of the ovule changes into the outer seed coat, which is called the testa.

**Final Answer**: After fertilization, the outer integument of the ovule changes into the testa (outer seed coat).
