Transcript Reproduction in Flowering Plants

Bell work 1/12/12
Some plants have flowers &
some do not. Some flowering
plants (plants with flowers)
produce fruit.
What part of the flower is
the fruit? (You may give a
specific name or talk about
where the part is or what it
does.)
Objectives
• Match the flower parts with their
reproductive functions. (SPI 0707.4.2)
– Take notes on flower parts
– Create a flower foldable
Parts of the Flower
The Parts of a Flower
• Most flowers have
four parts:
• sepals,
• petals,
• stamens,
• carpels.

The parts of a flower
• Sepals protect the
bud until it opens.
• Petals attract
insects.
• Stamens make
pollen.
• Carpels grow into
fruits which
contain the seeds.
Explain to your elbow partners about the four
main parts of a flower and what their
function is.
Stamen (male)
• Anther: pollen
grains grow in the
anther.
• Filament- long
thread that holds
the anther.
• When the grains
are fully grown, the
anther splits open.
Pistil (female)
•
•

•
Stigma
Style
Carpel (ovary)
Ovules (eggs)
•Stigma:
•Style:
•Ovary: contains the ovules
•Ovules: the lower part of the pistil that produces eggs in
ovules
Elbow Partners
Pollination
• Flowering plants
use the wind,
insects, bats, birds
and mammals to
transfer pollen
from the male
(stamen) part of
the flower to the
female (stigma)
part of the flower.
Pollination
• A flower is
pollinated when a
pollen grain lands
on its stigma.
• Each carpel grows
into a fruit which
contains the seeds.
• Seeds are baby
plants!!!
Directions for Foldable
• Use page 166-172 to color, label, and define the following:
– Flower, petal, stigma, style, ovary, pistil, sepal, filament,
anther, stamen, seed, fruit, photosynthesis, leaves, & stem
Draw, color, label, & define: roots
Draw & color: soil/ ground
Extra Credit: Draw & color background with the sun,
rainwater going into the soil for the roots, & insects,
such as bees, going through pollination.
