2.Was it challenging, easy or just right? 3. Did you feel prepared for the Multiple

Choice? 4. Any more questions about Common

Assessment?

Draw these shapes in your notebook.Brainstorm what you

know about plants with your table

Describe the

plants your

tables. What do all plants need?

What are 4 characteristics of all plants?

Define “autotroph.”

What are the three basic parts of all plants?

1. What are characteristics of all plants?

2. What are the needs of plants?

3. Are humans autotrophs?4. Do plants have organs?

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?

http://plantsinmotion.bio.indiana.edu/plantmotion/earlygrowth/germination/germ.html

A seed contains a baby plant, stored up energy, and a protective seed coat.

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.

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.

6. The ____________ plant gets_________ and pushes out of the soil. 7. The ______________ of the shoot straightening up _______________ the seed leaves above the ground.

Name a force that helps seeds become seedlings.

Person number 4 will go to the window and observe their plant.

1. What is the difference between xylem and phloem?

2. What is the function of seeds?3. What “wakes” up seeds and

begins the growing process?4. Why would farmers soak their

seeds in water before planting them?

What would happen if a seedling got turned around?

Would the roots grow up and the shoots grow downward?

Shoot

root

http://plantsinmotion.bio.indiana.edu/plantmotion/movements/tropism/tropisms.html

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

Cell Wall

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 ORGANELLES provide structure for the plant cell? (there are 2)

What happens when the VACUOLE is full of water?

What happens when the VACUOLE loses water?

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.

http://dsc.discovery.com/videos/life-venus-flytrap-catches-flies.html http://dsc.discovery.com/videos/life-creeper-plants-climb-trees.html 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

1. A plants’ roots grow toward the water.

2.

3. A plants’ leaves curl up when touched.4.

1. Name four stimuli that plants respond to.

2. What is a tropism?

3. How do plants respond to stimuli? By moving or growing?
