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

The Parts of a Flower

• Most flowers have four parts
• sepals,
• petals,
• stamens,
• carpels.

6
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.

7
Elbow Partners

• Explain to your elbow partners about the four
  main parts of a flower and what their function
  is.

8
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.

9
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

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.

12
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.

• 3 things I learned
• 2 questions I have
• 1 way I can relate this lesson to my daily life
  and how it benefits me
