Biology · SEXUAL REPRODUCTION IN FLOWERING PLANTS

हिन्दी

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Geitonogamy is functionally cross-pollination but genetically it is similar to autogamy. Reason (R): Geitonogamy involves transfer of pollen grains to a stigma mediated by a pollinating agent, but the pollen grains originate from the same plant. In the light of the above statements, choose the correct option:

  1. Both (A) and (R) are true and (R) is the correct explanation of (A)
  2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A)
  3. is true but (R) is false
  4. is false but (R) is true

Correct answer · Option 1

Both (A) and (R) are true and (R) is the correct explanation of (A)

Explanation

Since it requires an external pollinator it is functionally cross-pollination, but since pollens come from the same plant/genetic individual, genetically it is autogamous.
