Study Notes

Flower Structure and Function

The main function of a flower is to reproduce.
Petals are the brightly colored parts of a flower.
Stamen is the male reproductive part of a flower.
Anther is the structure on the stamen that produces pollen grains.
Pistil is the female reproductive part of a flower.
Stigma is the part of the pistil that receives pollen grains.

Reproduction in Plants

Plants can reproduce in two main ways: sexually and asexually.
Sexual reproduction involves the fusion of male and female gametes.

Pollination and Fertilization

The transfer of pollen grains from the anther to the stigma is called pollination.
After successful pollination, a pollen tube grows towards the ovule.
The fusion of a sperm cell from the pollen with an egg cell in the ovule is called fertilization.
Fertilization leads to the formation of a zygote, which develops into a seed.
