How NEET Tests 'Plant Kingdom'
This is a high-yield chapter (about 2-3 questions/year). From the previous-year papers, the reliably tested areas are:
- Algae - matching each class to its pigments, stored food and examples (fucoxanthin, mannitol, floridean starch, carrageen, agar).
- Life cycles - haplontic / diplontic / haplo-diplontic, the dominant phase in each group, and sequencing the events of bryophyte and pteridophyte life cycles.
- Bryophytes & pteridophytes - gametophyte vs sporophyte dominance, gemmae, prothallus, homospory vs heterospory, the seed-habit precursor.
- Gymnosperms - naked seeds, coralloid roots/mycorrhiza, and the anatomy traps (no vessels; no companion cells/sieve tubes).
- Angiosperms - double fertilisation and the embryo sac.
Below are genuine NEET previous-year questions from this chapter, followed by exam-pattern practice in the same styles.
