A: Each cell fo the sporogenous tissue is capable of giving rise to a microsproe tetrads
R: Most abundant microspore tetrads is the product of simultaneous cytokinesis

Options

A. if both assetion A reason are ture and the reason is the correct explanation of the assertion then mark
B. if both assertion & reason are ture and the reason is not the correct explanation of the assertin then mark
C. if assertion is true statement but reason is false then mark
D. if both assertion and reason are flase statements then mark

Answer

To analyze the given statements regarding the assertion (A) and reason (R), we will evaluate each part step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states: "Each cell of the sporogenous tissue is capable of giving rise to a microspore tetrad."
- In flowering plants, specifically angiosperms, the sporogenous tissue is found within the anther of the stamen. This tissue is responsible for producing pollen grains.
- Each cell in the sporogenous tissue can develop into a pollen mother cell (PMC), which undergoes meiosis to produce four haploid microspores. These microspores can then form tetrads.

2. **Evaluating the Truth of the Assertion (A)**:
- Since each cell in the sporogenous tissue can indeed give rise to microspore tetrads through meiotic division, the assertion is **true**.

3. **Understanding the Reason (R)**:
- The reason states: "Most abundant microspore tetrads is the product of simultaneous cytokinesis."
- Cytokinesis is the process of cell division that follows mitosis or meiosis, where the cytoplasm of a parental cell divides into two daughter cells.
- In the context of microspore formation, simultaneous cytokinesis refers to the division of the pollen mother cell after meiosis, resulting in the formation of microspore tetrads.

4. **Evaluating the Truth of the Reason (R)**:
- The statement regarding simultaneous cytokinesis leading to the formation of microspore tetrads is also **true**. This is because the microspores are formed in groups of four due to this type of cytokinesis.

5. **Determining the Relationship Between A and R**:
- The assertion discusses the capability of sporogenous tissue cells to form microspore tetrads, while the reason explains how these tetrads are formed through cytokinesis.
- Although both statements are true, the reason does not directly explain the assertion. The assertion is about the potential of sporogenous cells, while the reason is about the process of tetrad formation.

6. **Conclusion**:
- Since both the assertion and reason are true but the reason does not explain the assertion, the correct option is that both are true, but the reason is not the correct explanation of the assertion.

### Final Answer:
- The correct option is: **Both assertion and reason are true, but reason is not the correct explanation of assertion.**
