Identify the wrong statement/s regarding post-fertilization development .

Options

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

Answer

To identify the wrong statement regarding post-fertilization development, we will analyze each statement provided in the question step by step.

### Step 1: Analyze the First Statement
**Statement:** The oak tree ball develops into the pericarp.

**Analysis:** This statement is correct. The pericarp is the part of the fruit that develops from the ovary wall after fertilization. In the case of the oak tree, the acorn (oak tree ball) develops into the pericarp as it matures.

### Step 2: Analyze the Second Statement
**Statement:** The outer integument of the ovule develops into the tegmen.

**Analysis:** This statement is incorrect. The tegmen is actually formed from the inner integument of the ovule, not the outer integument. The outer integument contributes to the seed coat but does not develop into the tegmen.

### Step 3: Analyze the Third Statement
**Statement:** The triple fusion nucleus develops into the endosperm.

**Analysis:** This statement is correct. The endosperm is formed through a process called triple fusion, where one male gamete fuses with two polar nuclei, resulting in a triploid cell that develops into the endosperm.

### Step 4: Analyze the Fourth Statement
**Statement:** The ovule develops into a seed.

**Analysis:** This statement is also correct. After fertilization, the ovule transforms into a seed, containing the embryo that develops from the fertilized egg.

### Conclusion
Based on the analysis, the only incorrect statement regarding post-fertilization development is the second statement: "The outer integument of the ovule develops into the tegmen."

### Final Answer
The wrong statement regarding post-fertilization development is:
- The outer integument of the ovule develops into the tegmen.
