Study Notes
- Flowers house the gametophyte generation in sexual reproduction in angiosperms.
- Modified stems with modified leaves bear flower structures with four whorls: Calyx (outermost, made of sepals), Corolla (second, made of petals), Androecium (third, male reproductive structures), and Gynoecium (innermost, female reproductive structures).
- The Carpel is the female part of the flower, with the ovary containing ovule (megagametophyte), stigma where pollen lands, and style leading to the ovary.
- The Stamen is the male part of the flower, with anther containing pollen grains and filament supporting the anther.
- Perfect flowers contain both male and female parts, while imperfect flowers can be staminate (only male unit) or carpellate (only female unit).
- Male gamete production involves microsporogenesis and microgametogenesis in the anther, leading to the development of pollen grains and sperm cells.
- Female gamete production involves megasporogenesis and megagametogenesis in the ovule, resulting in the development of the embryo sac with egg cells and polar nuclei.
- Pollination is followed by fertilization in plants, involving the transfer of pollen to the stigma, growth of a pollen tube to the embryo sac, and the production of sperm cells for fertilization.
