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): The pollen tube enters the embryo sac through the micropylar end into one of the synergids. Reason (R): The filiform apparatus present at the micropylar tip of the egg cell guides the entry of the pollen tube. In the light of the above statements, choose the most appropriate answer from the options
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is not correct
- D(A) is not correct but (R) is correct
Correct answer
C. (A) is correct but (R) is not correct
Step-by-step solution
Assertion (A) is correct because during fertilization in angiosperms, the pollen tube typically enters the embryo sac at the micropylar end and penetrates into one of the synergids. Reason (R) is incorrect because the filiform apparatus is present at the micropylar tip of the synergids, not the egg cell. It is this apparatus in the synergids that guides the entry of the pollen tube. Therefore, (A) is correct but (R) is not correct. Answer: (A) is correct but (R) is not correct
