NEET-UG Pattern Practice — The Final Drill
This section gives you NEET-pattern single-best-answer MCQs on the most-tested concepts of the chapter. NEET MCQs differ from Board questions in three important ways:
- Format: Single best answer from 4 options. No partial credit. ~1 minute per question.
- Style: Tests specific facts (Latin names, exact numbers, exact NCERT phrases) and concept-application traps.
- Pattern: Recurring patterns include — ploidy questions, "which is unique to angiosperms?", "match Latin name to phenomenon", "trace pollen tube path."
We've curated 15 questions representing the highest-frequency NEET MCQ patterns from this chapter. Each comes with a brief solution focusing on the discriminating fact.
Tip: When you re-attempt these later (a week, a month before NEET), aim to finish all 15 in under 12 minutes with 90%+ accuracy. That's NEET-ready.
Q1. Which of the following is unique to angiosperms?
(A) Microsporogenesis (B) Double fertilisation (C) Pollen tube (D) Embryo development
Answer: (B) Double fertilisation
Solution: Double fertilisation (syngamy + triple fusion) is unique to angiosperms. Other plant groups (gymnosperms, pteridophytes, bryophytes) have only single fertilisation. Microsporogenesis, pollen tubes, and embryo development also occur in gymnosperms.
Q2. The mature embryo sac of an angiosperm is:
(A) 7-celled, 7-nucleate (B) 8-celled, 8-nucleate (C) 7-celled, 8-nucleate (D) 8-celled, 7-nucleate
Answer: (C) 7-celled, 8-nucleate
Solution: 7 cells, 8 nuclei. The extra nucleus is the second polar nucleus in the central cell. Most-tested NEET fact in the entire chapter.
Q3. Sporopollenin is found in:
(A) Intine of pollen (B) Exine of pollen (C) Nucellus of ovule (D) Funicle of ovule
Answer: (B) Exine of pollen
Solution: Sporopollenin builds the EXINE (outer wall) of pollen. Intine is cellulose + pectin. Sporopollenin is the most resistant biological material known.
Q4. The ploidy of the endosperm in angiosperms is:
(A) n (B) 2n (C) 3n (D) 4n
Answer: (C) 3n
Solution: Angiosperm endosperm = 3n (triploid), from triple fusion (1 male gamete + 2 polar nuclei). Gymnosperm endosperm is n. Drill this contrast.
Q5. Coconut water is biologically:
(A) Liquid mesocarp (B) Free-nuclear endosperm (3n) (C) Cellular endosperm (D) Embryonic fluid
Answer: (B) Free-nuclear endosperm (3n)
Solution: Coconut water = free-nuclear, triploid (3n) endosperm. The white meat is the cellularised endosperm. NCERT-explicit example.
Q6. Pollen of which plant is famous for causing severe allergy in India?
(A) Hibiscus (B) Rosa indica (C) Parthenium hysterophorus (D) Mangifera indica
Answer: (C) Parthenium hysterophorus
Solution: Parthenium hysterophorus (carrot grass / congress grass) — entered India as a wheat contaminant, causes asthma, bronchitis, dermatitis. NCERT explicitly names this species.
Q7. Yucca is pollinated by:
(A) Honey bee (B) Tegeticula moth (C) Hummingbird (D) Bumble bee
Answer: (B) Tegeticula moth
Solution: Yucca's sole pollinator is the female Tegeticula moth — textbook obligate mutualism. Moth lays eggs in ovary while pollinating. Both species depend on each other.
Q8. Most common type of ovule found in angiosperms is:
(A) Orthotropous (B) Anatropous (C) Campylotropous (D) Amphitropous
Answer: (B) Anatropous
Solution: Anatropous (inverted) ovule is dominant. Body of the ovule is inverted 180° on the funicle so the micropyle ends up close to the hilum. Minimises pollen tube travel distance.
Q9. Pollen tube enters the embryo sac via:
(A) Antipodal cell (B) Synergid (via filiform apparatus) (C) Egg cell directly (D) Polar nucleus
Answer: (B) Synergid (via filiform apparatus)
Solution: Pollen tube enters ONE of the 2 synergids via the FILIFORM APPARATUS (chemoattractive cell-wall thickening). The synergid degenerates and releases the 2 male gametes into the embryo sac. The pollen tube does NOT enter the egg directly.
Q10. Which one of the following is correctly matched?
(A) Apple — true fruit (B) Banana — apomixis (C) Citrus — polyembryony (D) Wheat — non-albuminous
Answer: (C) Citrus — polyembryony
Solution: Correct: Citrus shows polyembryony (multiple embryos per seed via adventive embryony). Apple = FALSE fruit; Banana = PARTHENOCARPY (not apomixis); Wheat = ALBUMINOUS (endosperm persists). Memorise these correct pairings.
Q11. Pollen grain at the time of shedding in cereals (e.g., wheat, rice) is:
(A) 1-celled (B) 2-celled (C) 3-celled (D) Multinucleate
Answer: (C) 3-celled
Solution: Cereals (grasses — wheat, rice, maize) shed 3-CELLED pollen (1 vegetative cell + 2 male gametes). ~60% of angiosperms shed 2-celled pollen; the remainder are shed at the 3-celled stage.
Q12. Parthenocarpy is best illustrated by:
(A) Citrus (B) Mango (C) Apple (D) Banana
Answer: (D) Banana
Solution: Cultivated banana = classic parthenocarpic example (fruit develops without fertilisation, hence seedless). Citrus and Mango show POLYEMBRYONY (different phenomenon). Apple is a FALSE FRUIT (different again).
Q13. The phenomenon of seed formation without fertilisation is called:
(A) Polyembryony (B) Parthenocarpy (C) Apomixis (D) Cleistogamy
Answer: (C) Apomixis
Solution: Apomixis = seed without fertilisation (clonal seeds). Parthenocarpy = fruit without fertilisation (seedless fruits). Polyembryony = many embryos per seed. Cleistogamy = closed flowers with assured self-pollination.
Q14. Which of the following is the LARGEST inflorescence in the world, attracting pollinators by foul odour?
(A) Yucca (B) Amorphophallus titanum (C) Hibiscus rosa-sinensis (D) Aristolochia
Answer: (B) Amorphophallus titanum
Solution: Amorphophallus titanum has the world's tallest inflorescence (~6 feet) and attracts pollinators with the smell of rotting flesh — attracting carrion flies and beetles. NCERT-explicit.
Q15. Pollen banks preserve pollen at:
(A) +4°C (B) −20°C (C) −80°C (D) −196°C (liquid nitrogen)
Answer: (D) −196°C (liquid nitrogen)
Solution: Pollen banks use liquid nitrogen at −196°C for cryopreservation. At this temperature, all enzymatic activity ceases, preserving pollen viability for years. Used in modern plant breeding.
