How this Chapter is Tested in NEET
Sexual Reproduction in Flowering Plants is one of the highest-scoring chapters of the whole syllabus - NEET usually sets three to five questions from it every year, and they are largely fact-based, so they are very much within reach.
The recurring favourites are:
- Ploidy of structures (n / 2n / 3n) - the single most repeated theme; know the zygote (2n), endosperm (3n), synergid/egg/antipodal (n), nucellus/perisperm (2n).
- The embryo sac - '8-nucleate, 7-celled', the egg apparatus, and the number of meiotic and mitotic divisions.
- Anther and pollen - wall layers, the tapetum, sporopollenin, and microsporogenesis.
- Pollination - autogamy vs geitonogamy vs xenogamy, cleistogamy, wind vs water pollination, and special examples (Vallisneria, Zostera, Yucca-moth, Ophrys sexual deceit).
- Double fertilisation - syngamy and triple fusion, and the fate of the two male gametes.
- Post-fertilisation - endosperm types, perisperm, aleurone layer, false fruit (apple), parthenocarpy (banana), apomixis and polyembryony.
The set below combines genuine NEET previous-year questions with a few exam-pattern questions in the same style. Work each one fully - the explanation gives the reasoning, not just the key.
Strategy: when a question names a structure, immediately recall its ploidy and its origin (which floral part it develops from); a large fraction of the marks in this chapter turn on exactly those two facts.
