Identify the wrong statements regarding post fertilisation development

Options

A. The ovary wall develops into pericarp
B. The outer integument of ovule develops into tegmen
C. The product of triple fusion develops into endosperm
D. The ovule develops into seed

Answer

**Step-by-Step Solution:**

1. **Understanding Post-Fertilization Development**: Post-fertilization development involves several changes in the ovule and ovary after fertilization occurs. The ovule develops into a seed, and the ovary develops into a fruit.

2. **Analyzing the Statements**:
- **Statement 1**: "The ovary wall develops into pericarp."
- This statement is correct. The ovary wall indeed develops into the pericarp, which is the outer layer of the fruit.

- **Statement 2**: "The outer integument of ovule develops into tegment."
- This statement is incorrect. The outer integument of the ovule develops into the testa (seed coat), while the inner integument develops into the tegment.

- **Statement 3**: "The product of triple fusion develops into endosperm."
- This statement is correct. The triple fusion involves the fusion of two polar nuclei and one male gamete, resulting in a triploid structure that becomes the endosperm.

- **Statement 4**: "The ovule develops into seed."
- This statement is also correct. After fertilization, the ovule develops into a seed.

3. **Identifying the Wrong Statement**:
- From the analysis, the only incorrect statement is the second one: "The outer integument of ovule develops into tegment."

**Final Answer**: The wrong statement regarding post-fertilization development is: "The outer integument of ovule develops into tegment."
