 Area of Focus: Parts of a Flower.

• What is does the perfect flower look like?
Copyright © 2010 Ryan P. Murphy

• A Perfect Flower: A flower that has both
the male parts and female parts in the
same flower.
Male
Female

• Imperfect Flower: A flower that has either all
male parts or all female parts, but not both
in the same flower.

• Flowers and Fruits Available Sheet

• Please record this picture in your journal.

• Stamen – Male part of flower (sperm).
– -
– -

• Activity! Flower Dissection.

– When we remove a piece of the flower, line
up the parts of the flower on the sticky side of
the clear tape provided.

– When we remove a piece of the flower, line
up the parts of the flower on the sticky side of
the clear tape provided.
– They will be taped into your journal.

• Activity! Please locate the stamen on your
flower and label your drawing.

• Filament: Supports the anther.

• Anther: Part of the stamen that holds the
pollen.

• Please locate the filament and the anther
on the flower. Look for pollen on anther.
– Label filament and anther on your drawing.

• Pistil: Female part of flower (egg).

• Activity! Please locate the pistil (female
part of flower) and then label it below.

• Stigma: Sticky bulb in the center of the
flower. Receives the pollen grains.

“You tell Spiky
Spruce that if he
touches Stevey
Stoma than
Susan Stigma is
going to become
very upset.”

• Activity! Please locate the stigma on your
flower and then label it as shown below.
– Check to see if it is sticky.

• Style: Long stalk that the stigma sits on
top of.

• Activity! Please locate the style (attached
with stigma) and label it below.

• Ovary: On bottom of the flower, has the
seeds inside and turns into the fruit.
Contains the ovules.

• Activity! Find the Ovary and then label
your picture accordingly.

• Ovule: The part of the ovary that becomes
the seeds.

• Activity! Locate the ovule and cut in half
and look for the early seeds. Label the
ovules in your journal.

• Petal: The colorful, often bright part of the
flower.
– They attract pollinators and are pretty .

• Coevolution: The evolution of two or more
species, each adapting to changes in the
other.

• Dispersive mutualisms: One species
receives food in exchange for moving the
pollen or seeds of its partner.

• Pollination – Insects transfer pollen from
one flower to the next, insects gets nectar.

• Flowers attract pollinators through…
–Fragrance (smell)

• Flowers attract pollinators through…
–Fragrance (smell)
–Nectar (food)
–Color (sight)

• Question! Why are bees so efficient at
finding nectar in flowers and pollinating
flowers?

• They see the world in the Ultra-violet of
UV spectrum.
– Note the bulls eye below.

• Many insects, including bees see the
world and flower in UV (ultra-violet).
– Note the red bulls eye / target in UV.

• Many insects, including bees see the
world and flower in UV (ultra-violet).
– Note the red bulls eye / target in UV.
Target makes it easier to see and then
pollinate. Easy identification. (Fast Food)

• No fancy flower or nectar = Wind pollination
?????????

???

• Activity! Locate the petals and place them
on to your tape. Label your drawing in
your journal.

• Sepal: Green leaves that cover the outside
of a flower bud to protect the flower before
it opens.

• Activity! Locate the sepals, place it, and
then label the sepals on your drawing in
your journal.

• Quiz Wiz 1-10. Name that part of the flower.
Same answer can be used more than once.

• Bonus: Name the Movie
“Hey you.” “Did
you know that
the
anther, pollen, a
nd filament are
the male part of
the flower, did
you, huh?”

• Answers 1-10. Name that part of the
flower. Same answer can be used more

 New Area of Focus: Matured Ovaries

• Activity! How many fruits can you name?
– Everyone stand, when it comes to you name
a fruit, if you can’t name one, or you name a
repeated fruit , then your out. Play until one
winner.

• A few exotic fruits that you may not know
about.
– Durian, so smelly, it’s outlawed in many public
places.

• Dragonfruit: Native to Mexico

• Passion Fruit: South America

• Kiwano: “Horned Cucumber”

• Cherimoya: South America “Custard Apple”

• Mangosteen: Pacific Islands

• Health alert!

• Health alert! Many fruits are deadly
poisonous.

• Health alert! Many fruits are deadly
poisonous.
– Don’t just eat fruits because they look good.

• Watch out! Children will often eat wild
berries because they look like delicious
berries and candy they are use to.

– Which picture are blueberries?

• Which are blueberries, and which are
poisonous berries?

• Which are blueberries and which are
poisonous?

• Try and figure out what picture is beneath
the boxes.
– Raise your hand when you know. You only
get one guess.

• The ovary in the flower contains the
seeds.

• The ovary in the flower contains the
seeds. The ovary then becomes the fruits
with the seeds inside.

 Fruit: The matured ovary in the pistil.
Contains the seed.

• The terms fruit and vegetable are somewhat
confusing because they have both a botanical
and a common usage. Botanically, a fruit
always develops from a flower and is
composed of at least one ripened ovary.
Botanically, a vegetable is any edible part of
a plant other than the flower.

• Quiz Wiz 1-10 Is it a fruit or vegetable?

• Answers 1-10 Is it a fruit or vegetable?

• Bonus: Name the main character in the
movie A Bugs Life.

• Bonus # 2 Who is this? Ronnie James Dio

• Strawberries develop from flowers with
many pistils.

• The term berry means that seeds are
inside of the fruit.

I think this is a
berry, I don’t
see any seeds
on the
outside.

• Yum! Look at this delicious berry.

• Another delicious berry. Yum.

• Multiple Fruits: Form from a cluster of
several flowers.

• Dehiscent: A dry fruit that splits at maturity
releasing the seeds.

• Activity! Fruit Dissection
– Please draw and label each fruit in your journal.
– What type of fruit it is? (From notes)
– Exocarp – (exo=outside).
– Mesocarop – (meso = middle).
– Endocarp – (endo = inner).
– Where attaches to plant (stem)
• Example – next slide.

• This is a plume, or simple fruit. It developed
from one ovary and has one seed.
– Has a very fleshy mesocarp and thin exocarp.
