Key terms

Sexual reproduction: A method of reproduction involving two parent plants that contribute DNA through gametes to form a seed
Gametes: Sex cells that carry half the genetic information of a parent plant
Stamen: The male reproductive organ of a flower, consisting of the filament and the anther
Anther: The part of the male organ (stamen) that produces and stores pollen
Filament: The thin stalk that supports the anther
Stigma: The sticky part of the female reproductive organ that collects incoming pollen grains
Style: The stalk that holds the stigma up in position
Ovary: The base of the female reproductive structure that protects the ovules
Ovules: Structures located inside the ovary where the female gametes (ova) are produced
Ova: The female gametes (singular: ovum)
Producers: Organisms like plants that make their own food using sunlight, water, and carbon dioxide through photosynthesis

What this lesson covers

How well do you know each one? Be honest: red means go back over it.

Name the male parts of a flower and describe what each one does
Name the female parts of a flower and describe what each one does
Explain what gametes are and where they are found in a flower
Describe pollination and explain how it differs from fertilisation
Explain how the structure of a flower helps it attract pollinators

Test yourself
