In each of the following questions, a statement of Assertion is given followed by corresponding statement of Reason of the statement, mark the correct alternative as directed below.
Assertion : Division of cytoplasm is called cytokinesis.
Reason: This cytokinesis is due to the cell plate formation or by cleavage

Options

A. If both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
B. If both Assertion and Reason are true, but Reason is not the correct explanation of Assertion
C. If Assertion is true, but Reason is false.
D. If both Assertion and Reason are false.

Answer

To solve the question, we need to analyze both the Assertion and the Reason provided.

**Step 1: Analyze the Assertion**
- The assertion states: "Division of cytoplasm is called cytokinesis."
- This statement is true. Cytokinesis is indeed the process that follows mitosis or meiosis, where the cytoplasm of a parental cell is divided into two daughter cells.

**Step 2: Analyze the Reason**
- The reason states: "This cytokinesis is due to the cell plate formation or by cleavage."
- This statement is also true. Cytokinesis occurs through two main mechanisms: in plant cells, a cell plate forms, while in animal cells, cleavage furrow formation occurs.

**Step 3: Determine the Relationship**
- While both the assertion and reason are true, we need to determine if the reason correctly explains the assertion.
- The reason describes how cytokinesis occurs but does not explain why the division of cytoplasm is called cytokinesis. Therefore, the reason is not a proper explanation for the assertion.

**Conclusion: Mark the Correct Alternative**
- Since both the assertion and reason are true, but the reason does not adequately explain the assertion, the correct alternative is:
**Option 2: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.**
