Each table will receive a Ziploc bag, one cotton ball,
and one bean seed.
Write your table name and period at the bottom of
their bags (with a marker if possible).
Soak the cotton ball in water.
Flatten out the cotton ball, but don’t squeeze the
water out.
Bury the seed inside the cotton ball.
Open the Ziploc bag and tape the cotton ball with the
seed about 4 inches down inside the bag.
Grab a second cotton ball and soak it in water and
squeeze some more water into the cotton ball that
contains the seed.

Now zip shut the
bag.

Tape your bag to the
window, near your
period sign.

Using page 331, read about seeds. As you are
reading, complete your chart on seeds.
Answer these questions as well:
1. What are the three parts of a seed?
2. How do seeds sprout?


otion/earlygrowth/germination/germ.html
A seed contains a baby plant, stored up energy,
and a protective seed coat.
What do seeds
need?

Seeds need water to
sprout or grow.

Once the seed
receives water, it ”
awakens” or
germinates,

The seeds absorb so much water, that the
force of the water pressure pushes open the
seed.

The dry seed absorbs water, the plant cells
get bigger and the plant breaks out of the
seed.
6. The ____________ plant gets_________ and pushes out of the soil.
7. The ______________ of the shoot straightening up _______________ the seed leaves above the groun

The growing plant
gets larger and pushes
out of the soil.

The force of the shoot
straightening up pulls
the seed leaves above
the ground.

Name a force that helps seeds become
seedlings.
Person number 4 will go to the window

3. What “wakes” up seeds and begins the
growing process?
4. Why would farmers soak their seeds in
water before planting them?

around?
Would the roots grow up and the shoots grow
downward?


Plants are able to
sense gravity and
respond to changes
in position.

This response is
called geotropism.

Roots will bend and
grow downwards,
towards the center of
the Earth.

Shoots will bend and
grow upwards, or
away, from the surface
of the Earth.

Grown plants also
respond to
geotropism.

Their roots will grow
downward and their
shoots will grow
upward.

Name two forces that affect seedling growth.

Define geotropism.

Describe what happens to a plant that falls on
its side. Will the shoots and roots continue to
grow sideways?
1. List the levels of organization within
plants.
 2. What are the two major organ systems?
 3. What is the function of vascular tissue?
 4. Why do seeds get larger before they
sprout?
 5. Why do roots grow down and shoots grow
up?
Person number 2 will go to the window and
observe their plant.


What is geotropism?

How do you think plants will grow in space?

Draw a picture of what you think the shoots
and roots will look like.
Person number 3 will go to the window
and observe their plant.
 List the organelles in a plant cell.
 What is the function of the vacuole?
 What is the function of the cell wall?
 What provides structure for the plant?
 Draw a plant cell….
Vacuole

Use the materials in
your bin to create this
model.

What do you think the
paper box represents?

What do you think the
balloon represents?

Now deflate the
balloon.

What happens to
the paper box?

What is this
similar to in the
plant cell?

The Vacuole stores food, water, and waste for
the cell.

A plant cell has a LARGE vacuole that stores
water.

This LARGE vacuole helps support the cell.

A plant is made of
many plant cells.

When the vacuoles
are full of water,
they apply force
against the cell
wall—keeping the
plant upright.

But as the vacuole
loses water, there is
less pressure
against the cell wall.

The plant cells
droop and causes a
plant to look wilted.

What is a stimuli?
A change in the
environment
 What is a response?
 An organism’s
reaction to that
change
 Why must organisms
respond to stimuli?
 To maintain
homeostasis or keep
the organism healthy


Do plants respond to stimuli or changes in their environment? What are some examples you can think of?

 How do animals respond to
stimuli?
 How do you think plants would
respond to stimuli?

A plants growth response toward or away
from a stimulus is called a tropism.

Plants are sensitive and have developed
tropisms to help them survive.

Touch, light, water, and gravity are four
important stimuli that plants respond to.

Thigmotropism is how plants respond to
touch.

Watch the two videos and observe how the
plants respond to touch.

How does the vine respond to touch?
How does the Venus fly trap respond to touch?

Phototropism is how plants respond to light,
they will grow toward the light.

Watch the video and in your notes draw a
before and after picture of how the plant
responds to the light.

What does the plant do in response to the
light changing?

Hydrotropism is
how plants
respond to
water, roots will
grow toward the
water
How do plants
respond to gravity?
 Shoots grow upward
and roots grow
downward

What is this response
called?
 GEOTROPISM
