9. Male Parts
• The stamens are
the male
structures of
the flower.
• Made up of two
parts:
– Anther
– Filament
10. Male Parts
• Anther: top part
of the stamen,
that makes
pollen.
• Filament: this is
the stalk of the
Anther
11. Female Parts
• Pistil is the
female structure
of flower that
has 3 parts:
– Stigma
– Style
– Ovary
12. Female Parts
• Stigma:
– The pollen from
another flower
collects on the
stigma’s sticky
surface.
• Style:
– raises the stigma
away from the
Ovary
stigma
13. Female Parts
• Ovary protects the
ovules(egg).
• Once fertilization
has taken place it
will become the
fruit.
14. Write the correct words in the boxes:
stamens, stigma, petals, ovary, sepals
these attract
insects

where the
pollen is
made
pollen

where the
seeds grow

These protect
the flower
before it opens 3
Write the correct words in the boxes:
stamens, stigma, petals, ovary, sepals
16. Plants Reproductive Structures
• Cones: Gymnosperms
– Female cones contain the ovules which
contains the egg cell
– Male cones contain pollen which are like
sperm cells
• Flowers: Angiosperms
– Pistil: female part of flower
– Stamen: Male part of flower
18. • As the insect probes
for nectar, its body
rubs against the
stamens.
• Pollen gets stuck on
the insect’s legs.
• You can often see bees
with a heavy load of
yellow pollen on their
hind legs.
24. Seeds
• The seeds develop
inside the ovary,
which grows to
become the seed
pod or fruit.
25. Seed Dispersal
• The seeds are
dispersed; some by
animals, some by
the wind, some by
explosion and some
by water.

Please feel free to change anything in order to tailor these slides for your own use – you might wish to use this presentation as revision or as an introduction to the topic – I hope that it is of use!!
You might like to stop the show here and print out this slide. If you are using the Powerpoint version, go to Format, Background, Background Fill, and choose white, then click on Apply. This will change the background of this slide only to white so that you can print more economically. Change back to the original colour before you show the slides again. The children could now examine some flowers, identifying the parts, looking at them through a hand lens etc. When you think they are ready to move on to pollination, show the slides again from the beginning for revision, or start at the first pollination slide.
Slides 18 and 19 can be printed and used as worksheets – remember to change the background colour to white if you want to save ink (see notes with slide 10)– for black and white copying a white background is of course preferable anyway.
