Pollen grain: The pollen grains represent the male gametophytes. If you touch the opened anthers of Hibiscus or any other flower you would find deposition of yellowish powdery pollen grains on your fingers. Sprinkle these grains on a drop of water taken on a glass slide and observe under
Pollen grains are the male gametophytes that develop inside the anther. This is a fundamental concept because gametophytes are haploid structures involved in sexual reproduction. Many students confuse pollen grains with the diploid sporophyte or mistakenly think they're just spores rather than actual gametophytes capable of producing male gametes. Remember: pollen grains are multicellular male gametophytes, not simply pollen sacs or microsporocytes. They contain the male gametes (sperm cells) released during pollination. NTA tests this to ensure you understand alternation of generations in flowering plants and the role of male gametophytes in reproduction.
The plant parts which consist of two generations one within the other: (NEET 2020) (i) Pollen grains inside the anther (ii) Germinated pollen grain with two male gametes (iii) Seed inside the fruit (iv) Embryo sac inside the ovule
