NEETBotanySexual Reproduction in Flowering Plants
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 similar to autogamy. Reason (R): It involves the transfer of pollen grains from the anther to the stigma of another flower of the same plant. In the light of the above statements, choose the most appropriate answer from the options given
Options
- ABoth Assertion (A) and Reason (R) are correct and Reason (R) is the correct explanation of Assertion (A)
- BBoth Assertion (A) and Reason (R) are correct but Reason (R) is not the correct explanation of Assertion (A)
- CAssertion (A) is correct but Reason (R) is incorrect
- DAssertion (A) is incorrect but Reason (R) is correct
Correct answer
A. Both Assertion (A) and Reason (R) are correct and Reason (R) is the correct explanation of Assertion (A)
Step-by-step solution
The Assertion is a correct statement as per NCERT. Geitonogamy is functionally cross-pollination because it requires a pollinating agent to transfer pollen between different flowers. However, it is genetically similar to autogamy because the pollen grains come from the same plant, resulting in offspring that are genetically identical to the parent. The Reason correctly states the definition of geitonogamy: the transfer of pollen grains from the anther to the stigma of another flower of the same plant. The Reason pr
