Study Notes

Plant Reproduction and Seed Formation

The egg sac in a flower contains the egg cell and two polar nuclei which form the endosperm.
The receptacle is the thickened part of the pedicel from which flower parts grow.
Nectaries, located at the base of petals, produce nectar.
Female gametes are formed in the ovule contained in the ovary through meiosis.
Male gametes are produced inside the anther and form the pollen grain.
Pollination can be self-pollination or cross-pollination by insects, wind, or other methods.
Fertilization involves the fusion of male and female gametes to form a diploid zygote.
After fertilization, the ovule develops into the seed, with the zygote forming the seed embryo.
The seed structure includes the embryo, tough seed coat (testa), radicle, plumule, and cotyledons.
Fruit formation is essential for protecting and dispersing seeds, with seedless fruit varieties developed for consumer markets.
Seed dispersal occurs through animal, wind, water, and self-dispersal methods to ensure survival and minimize competition.
Dormancy is a period of reduced growth or metabolism, even when conditions are suitable for germination.
