7. The corolla is
made of the
petals – they
attract
pollinators
The stamens are
the male part of
the flower – they
are made of the
anther and the
filament. The
anther makes the
pollen.
The carpel is the
female part and made
of the stigma, style
and ovary. In the
ovary are ovules
which have the
female egg cell.
8. Flowers come in many shapes, colours and sizes.
They are usually specially adapted to particular
types of pollination.

10. There are two types of
pollination.
Cross pollination –
when pollen goes from one
plant to another of the same
type. This kind of
pollination results in
stronger plants.
The other type of pollination
is self pollination where
the pollen goes from the
anther to the stigma of the
same plant. This can result
in a genetically weaker plant
Pollination is the transfer
of pollen from the anther
to the sticky stigma by
wind, animals/insects or
water.
14. Brazilian Birthwort
The Brazilian birthwort uses
insects as pollinators. The putrid
odor of this species—like that of
rotting flesh—especially attracts
flies, which enter the plant and
become trapped overnight. While
they are trapped, they become
completely dusted with pollen.
They escape the following day as
the plant withers and are
attracted to other Brazilian
birthworts, which they then
inadvertently pollinate as they
enter and again become trapped.

16. Worker Honey Bee in the Field
As they fly from flower to flower, worker honey bees
collect pollen grains and pack them onto their hind
legs in special hair-fringed pockets known as pollen
baskets (shown here holding a glob of yellow pollen
on the hind leg). Nectar, the sweet liquid produced
by flowers, is sucked into the honey stomach, an
internal storage sac. In the hive, field bees deposit
their pollen pellets into empty storage cells of the
comb and regurgitate nectar to waiting hive bees.
The hive bees mix some nectar with the pollen to
make bee bread, a spoilage-proof larval food, and
gradually concentrate the rest of the nectar into
honey by dehydration.
17. Butterfly Pollinating a
Flower
Many species of butterflies eat
plant nectar. When these
butterflies land on a series of
flowers in search of food, they
brush their bodies against both
male and female floral
organs, inadvertently transferring
pollen from one flower to another.

19. Lawson Cypress
Branch
The Lawson cypress, like
all other coniferous
trees, is wind pollinated.
The tiny male “flowers”
are located at the ends of
the small
branchlets, where the
wind can easily pick up
and distribute their
pollen.
28. Lesser Burdock Plant
The lesser burdock plant has a fruit that is encased in a burr covered with
hooks. These hooks enable the burr to easily attach to the fur of passing
animals, which ensures wide-ranging dispersal of the seeds.
