What Sexual Reproduction in Flowering Plants covers

Topics in the NEET (UG) 2026–27 syllabus for this chapter.

  • Flower structure; development of male and female gametophytes
  • Pollination- types, agents and examples; outbreeding devices; pollen-pistil interaction
  • Double fertilization; post fertilization events- endosperm and embryo development, seed and fruit formation
  • Special modes- apomixis, parthenocarpy, polyembryony
  • Significance of seed and fruit formation

Past NEET questions on Sexual Reproduction in Flowering Plants

Try each one, then open the answer and explanation.

Question 1 · NEET 2025

How many meiotic and mitotic divisions need to occur for the development of a mature female gametophyte from the megaspore mother cell in an angiosperm plant?

  1. A.2 Meiosis and 3 Mitosis
  2. B.1 Meiosis and 2 Mitosis
  3. C.1 Meiosis and 3 Mitosis
  4. D.No Meiosis and 2 Mitosis
Show answer

Answer: C. 1 Meiosis and 3 Mitosis

Megaspore mother cell (2n) undergoes meiosis to produce 4 haploid megaspores. One functional megaspore develops into female gametophyte via 3 mitotic divisions, producing 8 nuclei (7 cells). So: 1 meiosis + 3 mitosis.

Question 2 · NEET 2025

Given below are two statement: One is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Both wind and water pollinated flowers are not very colourful and do not produce nectar. Reason (R): The flowers produce enormous amount of pollen grains in wind and water pollinated flowers. In the light of the above statements, choose the correct answer from the options given below:

  1. A.Both A and R are true and R is the correct explanation of A.
  2. B.Both A and R are true but R is NOT the correct explanation of A.
  3. C.A is true but R is false.
  4. D.A is false but R is true.
Show answer

Answer: B. Both A and R are true but R is NOT the correct explanation of A.

Wind/water-pollinated flowers are dull and nectar-less because they don't need to attract pollinators, not due to pollen amount. R states flowers produce enormous pollen, which is true but not the correct explanation for A.

Question 3 · NEET 2025

Given below are two statements: Statement I: Fig fruit is a non-vegetarian fruit as it has enclosed fig wasps in it. Statement II: Fig wasp and fig tree exhibit mutual relationship as fig wasp completes its life cycle in fig fruit and fig fruit gets pollinated by fig wasp. In the light of the above statements, choose the most appropriate answer from the options given below:

  1. A.Both statement I and statement II are correct
  2. B.Both statement I and statement II are incorrect
  3. C.Statement I is correct but statement II is incorrect
  4. D.Statement I is incorrect but statement II is correct
Show answer

Answer: D. Statement I is incorrect but statement II is correct

Statement I is incorrect because fig fruit is botanically a vegetable accessory fruit (syconium) and is considered vegetarian; it's not 'non-vegetarian.' Statement II is correct: the fig–wasp relationship is classic mutualism — wasp pollinates, fig provides oviposition site.

Question 4 · NEET 2025

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): A typical unfertilized, angiosperm embryo sac at maturity is 8 nucleate and 7-celled. Reason (R): The egg apparatus has 2 polar nuclei. In the light of the above statements, choose the correct answer from the options given below:

  1. A.Both A and R are true and R is the correct explanation of A.
  2. B.Both A and R are true but R is NOT the correct explanation of A.
  3. C.A is true but R is false.
  4. D.A is false but R is true.
Show answer

Answer: C. A is true but R is false.

In angiosperms, embryo sac at maturity is 8-nucleate, organized into 7 cells: egg cell + 2 synergids (egg apparatus) + 3 antipodals + 1 central cell with 2 polar nuclei. So A is true. R is false because egg apparatus includes egg cell + synergids, not polar nuclei; polar nuclei are in central cell.

Question 5 · NEET 2024

Pollen grains remain preserved as fossils due to the presence of :

  1. A.Epidermal layer
  2. B.Tapetum
  3. C.Exine layer
  4. D.Intine layer
Show answer

Answer: C. Exine layer

Fossil pollen grains preserve because exine is made of sporopollenin, highly resistant to decay, unlike other layers which degrade.
