Plant Reproduction and Flower Structure

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.
