What to Focus On
- Flower is the reproductive organ of angiosperms.
- Sporophyte is diploid and gametophyte is haploid.
- Gametophytic phase is highly reduced in flowering plants.
- A typical flower has four whorls.
- Anther is the terminal fertile part of the stamen.
- Dithecous anther has four pollen sacs.
- Microsporogenesis occurs by meiosis.
- One microspore mother cell forms four haploid microspores.
- Tapetum provides callase and sporopollenin precursors.
Common Mistakes to Avoid
Pollen grains are the male gametes.
A dithecous anther has two pollen sacs because it has two lobes.
The tapetum is just a protective layer and has no role in pollen formation.
