Question:

Assertion: Cells of the sporogenous tissue lying in the centre of the microsporangium, undergo meiosis to form tetrads of microspores.
Reason: Sporogenous tissues are diploid mass of homogenous cells .

Options:

Both assertion and reason are true and reason is the correct explanation of assertion.

Both assertion and reason are true but reason is not the correct explanation of assertion.

Both assertion and reason are false.

Assertion is true and reason is false.

Correct Answer:

Both assertion and reason are true and reason is the correct explanation of assertion.

Explanation:

The correct answer is Option (1) →Both assertion and reason are true and reason is the correct explanation of assertion.

Explanation:

  • Assertion: "Cells of the sporogenous tissue lying in the centre of the microsporangium, undergo meiosis to form tetrads of microspores."
    • This is true because sporogenous cells (microsporocytes) are diploid and undergo meiosis to produce haploid microspores (which later develop into pollen grains).
  • Reason: "Sporogenous tissues are diploid mass of homogenous cells."
    • This is also true because sporogenous tissue is indeed a diploid (2n) group of cells that gives rise to microspores via meiosis.
  • Correct Explanation:
    • The reason correctly explains the assertion because only diploid cells can undergo meiosis to produce haploid spores. If the sporogenous tissue were not diploid, meiosis would not occur, and microspores would not form.

Thus, both the assertion and reason are true, and the reason is the correct explanation of the assertion.
