Question
NEET 2022 (paraphrased): Regarding sexual reproduction in flowering plants, which of the following statements is correct? (a) microsporogenesis refers to forms embryo sac (b) megasporogenesis is characterised by forms pollen grains via meiosis (c) triploid endosperm — 3n, nutritive tissue (d) apomixis has no role in sexual reproduction in flowering plants
Solution — Step by Step
This option swaps the definitions. microsporogenesis is actually forms pollen grains via meiosis, not what (a) claims. So (a) is out.
Similarly, megasporogenesis means forms embryo sac. Option (b) is mismatched. Out.
This one reads correctly: triploid endosperm — 3n, nutritive tissue. Match with NCERT wording confirms it.
apomixis — seed formation without fertilisation — plays a real role in sexual reproduction in flowering plants, so option (d) is factually wrong.
Correct answer: (c) triploid endosperm — 3n, nutritive tissue.
Why This Works
NEET PYQs on sexual reproduction in flowering plants rely on definition swapping. The examiner takes two correct facts and pairs them with the wrong terms. If you know each fact cold, the MCQ dissolves in 20 seconds.
Alternative Method
For definition-swap MCQs, don’t read all four options first. Read option (a), decide true/false, then (b), and so on. This prevents confusion between similar-looking options.
NEET reuses the same fact set every 2–3 years with different distractors. Master the four NCERT facts on sexual reproduction in flowering plants listed here and you’ll handle almost any MCQ on this chapter.
Common Mistake
Students second-guess themselves when they see a familiar option listed as “wrong” in the stem. Trust the elimination — if you know the definition, stick with it.
Keep a one-page sheet of definitions for every NEET chapter. Revise only that sheet in the last 48 hours before the exam.
