Question
Which of these is mismatched?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Polar nuclei are involved in double fertilization in angiosperms, fusing with a sperm to form the triploid endosperm. The plumule is part of the embryo (the future shoot). They are not directly related. The other pairs are correct: egg+sperm form zygote; ovule becomes seed; ovary becomes fruit.
Hint
Which structure in the ovule is not a direct precursor to the embryonic plant part?
