Pollination
to produce a seed, the male cell in a pollen
grain must fertilize a female cell in the ovule.
For this to happen the pollen must travel from
its anther to the female stigma. in some
flowers, the pollen is small and light,
with wings, and is blown from
one flower to another
by the wind.

Bees and
Flowers
Bees help
pollination. as
a bee feeds on nectar
and pollen, more pollen inside
the flower sticks to the bee’s legs
and body and is carried by the
bee to the next flower, where
it pollinates the female parts.

nectar
Butterflies, moths, bats, and birds feed
on the sweet, energy-rich nectar inside
each flower. Bees convert nectar into
honey in the beehive.

Horticulture
From the beginnings of
civilization, people have cultivated
flowers for their scent and color.
today’s garden roses have been bred
from wild ancestors so that they
have larger, more numerous,
and more colorful petals, sweeter
scents, and a longer flowering time.
the art of gardening is
called horticulture.

wild Flowers and conservation
Many wild flowers are in danger of extinction. Marshes are
drained, and forests are felled for farmland and buildings,
so the flowers that grow there are destroyed. rare and
beautiful blooms are at risk because they are dug up
illegally by plant collectors.
to save rare flowers, the
places where they grow must
be protected. as forests
are cut down, thousands of
flowers are disappearing
even before they are
known to science.

Bird-oF-Paradise Flower
the bird-of-paradise plant
comes originally from
riverbanks in southern
africa and is now grown in
many parks and gardens.
each plant has bright
orange flowers that form
a shape that looks like the
head and beak of a bird of
paradise. the bird-of-paradise
flowers rise one after the other
from a long, stiff, green-pink casing.

smell attracts
butterflies,
bees, and
people, too.
