Select FALSE statement from the following.

Options

A. A persistent nucellus is called a perisperm.
B. The integuments of an ovule harden as tough protective seed coats
C. The micropyle remains as a small pore in the seed coat and facilitates entry of oxygen and water into seed during germination.
D. The general metabolic activity of the embryo is high post-fertilization

Answer

To solve the question of selecting the false statement from the provided options, we will analyze each statement step by step.

### Step-by-Step Solution:

1. **Statement 1: A persistent nucleus is called a peri-sperm.**
- **Analysis:** This statement is true. A persistent nucleus refers to the tissue that remains after fertilization and is known as peri-sperm. It provides nourishment to the developing embryo. Examples include black pepper and beet.
- **Conclusion:** This statement is **true**.

2. **Statement 2: The integument of ovule becomes hard in a tough protective seed coat.**
- **Analysis:** This statement is also true. The integument of the ovule develops into the seed coat after fertilization. The seed coat serves as a protective covering for the seed.
- **Conclusion:** This statement is **true**.

3. **Statement 3: The micropyle remains like a small pore in the seed coat and allows the entry of oxygen and water during germination.**
- **Analysis:** This statement is true. The micropyle is a small opening in the seed coat that facilitates the entry of water and oxygen, which are essential for the germination process.
- **Conclusion:** This statement is **true**.

4. **Statement 4: The general metabolic activity of the embryo is high after fertilization.**
- **Analysis:** This statement is false. After fertilization, the embryo enters a state of dormancy, where metabolic activity is low. The embryo does not actively develop until conditions are favorable for germination. During dormancy, processes such as respiration and cell division decrease significantly.
- **Conclusion:** This statement is **false**.

### Final Answer:
The false statement is **Statement 4**: "The general metabolic activity of the embryo is high after fertilization."
