Structures of a Flowering Plant
part 2
6.2.4: Summarize the basic functions of the structures of a flowering plant for defense, survival, and reproduction.
Discuss
3 things about flowers
using qualitative or quantitative
words
Essential Question
What are some of the structures plants use for reproduction?
?
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.
Ovary with ovule and seeds
Flower Parts
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.
