Solution

Reproduction in flowering plants:

  1. Plants contain the reproductive organs of both males and females in the flowers.
  2. Such flowers make male and female gametes and ensure that fertilization takes place so that new seeds are formed for the reproduction of plants.
  3. The development of a flower begins the sexual reproduction cycle in all flowering plants.
  4. The complete sexual cycle involves the following –
  1. Following meiosis, is the production of special reproductive cells. This occurs through the process of microsporangium in males and megasporangium in females.
  2. Pollination: The pollen grains are transferred from the anther of the male flower to the stigma of the female flower, enabling fertilization and resulting in the production of seeds.
  3. Fertilization: The male gametes fertilize the female gametes.
  4. Seed and fruit development: The fertilized egg cells grow in ovules and become seeds.
  5. Seed and fruit dissemination: Here seed leaves the fruit or flower.
  6. Seed germination: When germinated, these seeds become new plants.
