Lesson details

Key learning points

  1. Flowering plants reproduce sexually.
  2. Plant reproduction is important as plants are producers and provide food for all animals on Earth.
  3. Flowers contain male and female sex organs and gametes.
  4. Egg cells (ova) are female gametes.
  5. Pollen grains carry male gametes.

Keywords

  • Sexual reproduction - Sexual reproduction is the process of making offspring where half the DNA is passed on from each parent.

  • Ova - The female gametes of a plant are called the ova.

  • Pollen - The male gametes of a plant are carried in grains of pollen.

  • Anther - The anther is a male organ of a flower which makes pollen.

  • Stigma - The stigma is a female organ of a flower upon which pollen is deposited.

Common misconception

Plants do not reproduce sexually. Flowers are only produced to look attractive.

Show examples of the reproductive organs; discuss pollen and ova and relate them to gametes in humans.

Carry out flower dissections with different types of flower to identify the main organs.
