Parts of Plants and
Flowers
What are four MAJOR
parts of plants?
• Leaf
•Roots
•Stem
•Flower
Functions or Jobs

All plant parts have a purpose
– Collect sunlight and make food (where
photosynthesis happens)
– Collect water and minerals, hold plant in
the soil, and store food
– Attract insects and animals in order for
the plant to reproduce
– Transport water and nutrients throughout
the plant

GOOD JOB!!
The leaves are like the food factories of
the plant. They make the food for the
plant. Have you ever noticed how
plant leaves will lean towards the sun.
They are made for collecting sunlight
for photosynthesis!
ALRIGHT!!
Roots hold the plant in the ground to
help secure it. Roots also soak up
water and minerals for the plant.
Water is very important and is
necessary for photosynthesis. Roots
are also like a cellar for the plant to
store extra food.
GREAT!!
Flowers are where the reproductive
parts of many plants are. They look
and smell a particular way in order to
attract insects and animals who will
move the pollen and fertilize that plant
or another plant.
YIPEE!!
The stem is like a bundle of pipes that
carries water, minerals, food, and
other nutrients throughout the plants.
The xylem carries water and minerals
up and the phloem carries food and
nutrients down.
Summary
The
four main plant parts and their
jobs:
–Leaves: Collect sunlight and make food
(where photosynthesis happens)
–Roots: Collect water and minerals, hold
plant in the soil, and store food
–Flowers: Attract insects and animals in
order for the plant to reproduce
–Stems: Transport water and nutrients
throughout the plant
Parts of a Flower
A flower is were the reproductive parts
of the plant is held. Many parts are
inside of a flower. The major parts
are:
-Stamen
-Stigma
-Pistil
-Filament
-Ovary
-Eggs
-Pollen/Sperm
-Anther

Male Parts
The male parts of the flower help fertilize the egg of
the flower. These parts are usually in a place that can
be easily moved by insects and animals. The male parts
are the pollen/sperm, stamen, and filament. Notice that
the last two words have the word “men” in them.
REMEMBER- MEN=MALE PART
Pollen
Stamen
Filament
What Do you Remember?

Pollen is the same as _______
Eggs
Sperm
Powder
Great!
Pollen is the male sex cell of a flower. Sperm is another
way to refer to pollen.
Male Parts Continued

The stamen is where all the male parts
of the flower are.

Male Parts Continued

The filament is a tube like structure
that holds up the anther (a head-like
structure) that makes the pollen.

anther
filament
What do you know?

Click on the filament
Yes!!

Good job. The filament is a tube-like
structure that holds up the anther.
Uh Oh…

This is a female part called the style.
On the top is a part called the stigma.
We will learn about this later in the
lesson.
Oh no…

This is a female part called the ovary.
We will learn more about this later in
the lesson.
Oops..

This part is called the anther. This is
where the pollen is made.
What do you remember?
The stamen is the ______
reproductive part of a flower

Male
 Female

Well Done!

The stamen is part of the male
reproductive system of a flower along
with the pollen, filament and anther.
Shucks!
The male parts are the stamen, pollen,
anther and filament. Notice that
two words have the word “men” in
them.
REMEMBER- “MEN”=MALE PART
The Female Reproductive
Organs

The pistil is the term for all the female parts of a
flower. Each pistil includes an ovary (where the
eggs are produced; the female reproductive cells, a
style (a tube on top of the ovary), and a stigma
(which the pollen sticks to during fertilization).

Where is the stigma?
Click on the part of the flower that shows the stigma.
Nope

This is a petal. This is used for
attracting insects and animals.
Uh Oh…

This is a female part called the style.
This is where the pollen tube will be
formed.
Oh no…

This is a female part called the ovary.
Here is where the eggs are stored and
what will change into the fruit that we
eat.
Rats…

This is the part of the ovary where the
eggs are stored.
Good Job!

The stigma is on top of the style. It is
sticky so that the pollen grains will
stick to it.

Look closely at the arrows and the
words...you can do it.

Well done!


This is tricky… double check the word
order
Fertilization

Pollen must join with an egg to produce a seed. This process is
called pollination, and is often helped by animals like bees, which
fly from flower to flower collecting sweet nectar. As they visit
flowers, they spread pollen around, leaving it on some stigmas.
After a male's pollen grains have landed on the stigma during
fertilization, pollen tubes develop within the style, burrowing down
to the ovary, where the sperm fertilizes an egg cell. After
fertilization, this develops into a seed in the ovary.

What forms in the style during
fertilization?
Pollen grain
 Pollen tubes
 Pollen allergies

Not quite

Pollen grains are individual pollen
cells.
Bummer…

Flowers don’t have allergies, as far as
I know.
Terrific!!

Let’s move on to a summary…
Fertilization summary

Once the pollen lands on the stigma,
the pollen grain burrows down the
style by making a pollen tube until it
reaches where the eggs are stored in
the ovary. The pollen and egg join
together to form a seed (baby plant).
The ovary ripens and becomes the
fruit that we eat.
Summary
Male Reproductive parts
Stamen- all the male parts
Pollen-male reproductive cell
which makes a tube down the
style during fertilization in order
to join with the egg.
Anther-where pollen is
produced
Filament-a tube that holds up
the anther
Female Reproductive Parts
Pistil-all the female parts
Style-a tube that hold up the
stigma; where a pollen tube is
formed
Stigma-a sticky surface on the
top of the style where pollen
can collect
Ovary-where the eggs are
stored
