Assertion :- Cell division, DNA replication and cell growth have to take place in co-ordinated way.
Reason:- Cell division , DNA replication and cell growth in coordinated way ensure correct division and formation of progeny cell containing intact genomes.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are false.

Answer

### Step-by-Step Text Solution:

1. **Understanding the Assertion**: The assertion states that "Cell division, DNA replication, and cell growth have to take place in a coordinated way." This means that these processes should not occur randomly but should be synchronized to ensure proper cell function.

2. **Evaluating the Reason**: The reason given is that "Cell division, DNA replication, and cell growth in a coordinated way ensure correct division and formation of progeny cells containing intact genomes." This indicates that if these processes are coordinated, it leads to accurate cell division and the proper distribution of genetic material to the daughter cells.

3. **Linking Assertion and Reason**: The assertion and reason are closely related. The assertion emphasizes the need for coordination among cell division, DNA replication, and cell growth, while the reason explains why this coordination is necessary—namely, to ensure that the resulting progeny cells have intact genomes.

4. **Determining the Truth of Both Statements**: Both the assertion and the reason are true. The coordination of these processes is essential for maintaining genetic integrity during cell division.

5. **Conclusion**: Since both the assertion and the reason are true, and the reason provides a correct explanation for the assertion, the correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

### Final Answer:
The correct answer is: **Option 1** - Both assertion and reason are true, and the reason is the correct explanation of the assertion.
