Structures for ReproductionParts of the flowering plant that function in reproduction include:
Flowers • Flowers produce seeds. • Many flowers contain both male and female parts
needed to produce new flowers.

Flowers
• Flower petals are often colorful or have a scent to attract insects and other animals.

Parts of a flower
Stamen – Male Part of Flower (think men and male).• The male part of a flower that has an anther
on a stalk (filament). • The anther produces the pollen that contains
the sperm cells.

Parts of a flower
PistilThe female part of the flower that contains– The ovary, which contains the ovules where the
egg cells are produced. – The stigma, which is the sticky top where pollen
grains land. – The style, which is a stalk down which the pollen
tube grows after pollination has taken place.

Seeds
• The ovule contains the fertilized egg (embryo) which turns into a seed.
• A fruit is formed from the ovary which protects the seeds.
• Seeds have special structures that allow them to be dispersed by wind, water or animals.

Summary
• What are some of the structures plants use for reproduction?
Answer:• Flowers– Male parts produce
pollen.– Female parts produce
ovules.– Together they produce
seeds that ensure survival of the species.
