In?

Roots, stems,
leaves,
flowers, fruits,
and seeds
its easy to
remember
a plants six
parts. They
sound just
like a poem!

Can you name
some of the parts
of this plant?

seeds

A plant's parts
work together
to keep it alive.

Each plant part has several jobs.
The main job of roots, stems, and
leaves is to help a plant grow.
Flowers, fruits, and seeds help a
plant produce new plants.

Mosses dont have
flowers or seeds.

Not all plants have every part.
Stems, leaves, flowers, fruits,
and seeds can all come and go
during the life of a plant. All
plants have roots, though.

Most roots take in water from
the soil. The water holds
minerals the plant needs to
stay healthy. Lets look at
how much water roots take in.

What You Need:

plastic cling wrap

clear
jar

water

tape

knife

rubber band

permanent marker

ruler

dug-up
plant

Crabgrass is a good plant for
this experiment. Ask an adult
to help you find a plant that
is safe to dig up.

Steps:

Fill the jar with water almost to
the top.

Cover the jar tightly with the plastic
cling wrap. Use the rubber band to
hold the plastic wrap in place.

Mark the water
level on the jar
with the marker.

Have an adult use the knife to cut a
slit across the middle of the plastic
cling wrap.

Gently push the plants stem through the
slit in the plastic wrap. Tape around the
plants stem to seal up the slit. Then put
the jar in a sunny spot.

The plastic wrap
will keep the water
from evaporating.

After three
days, take the
plant out of the
jar. Measure
how far the
water level has
fallen in the jar.

Many factors play a
role in how much water
the roots took up. A
plants health or when
it was last watered can
make a difference.

Think It Through

Roots can take in a lot of
water. Were you surprised by
how much water the roots took
up? Try this experiment with
a different plant. First, predict
how much
water the
new plants
roots will
take up.
Then see
if your
prediction
was correct!

Some roots, such as
carrots, have an extra
job. They store food
for the plant.

What

Do

Plant

Stems

Do?

A plants
stem has an
important
job. The
stem holds
up the plant.
This lets the
leaves reach
sunlight so
they can
make food.

A vine has a very long
stem. The vine holds
itself up by climbing
things around it.

Tree trunks are stems that
bring a trees leaves closer
to the sun.

A stem is also a pathway.
Water from the roots goes
up the stem. Food from the
leaves goes down.

We can experiment to prove
that water travels up through
the stem. Lets find out
what happens when you put
carnation stems in colored water.

What You Need:

two
clear jars

water

spoon

red and blue
food coloring

scissors

two white
carnations
with long stems

Steps:

Fill the jars a little more than
halfway with water.

Add drops of red food coloring to
one jar. Then add drops of blue
food coloring to the other. Stir the
water in each jar well.

The more food coloring
you add, the more obvious
the experiments results
