  and squeeze some more water into the cotton ball
  that contains the seed.

30
How does a seed become a seedling?

  earlygrowth/germination/germ.html

31
What is a seed?

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

32
What do seeds need?

• Seeds need water to sprout or grow.
• Once the seed receives water, it awakens or
  germinates,

33
What happens next?

• The seeds absorb so much water, that the force
  of the water pressure pushes open the seed.

34
Another way to say it..,

• The dry seed absorbs water, the plant cells get
  bigger and the plant breaks out of the seed.

35
Another way to say it
6. The ____________ plant gets_________ and
pushes out of the soil. 7. The ______________
of the shoot straightening up _______________ the
seed leaves above the ground.

• 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.

  phloem?

  before planting them?

39
Big Question

• What would happen if a seedling got turned
  around?
• Would the roots grow up and the shoots grow
  downward?

40
This is what happens
41
Describe the seedlings in your notes.
Shoot
root
42
Why does this happen?

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

43
Why does this happen?

• Plants are able to sense gravity and respond to
  changes in position.
• This response is called geotropism.

44
Why does this happen?

• 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.

45
Not just for seedlings.

• Grown plants also respond to geotropism.
• Their roots will grow downward and their shoots
  will grow upward.

46
Thinking Ticket

• 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?

• Draw a plant cell.

Cell Wall
Vacuole
53
Explore a plant cell model

• 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?

54
Explore a plant cell model

• Now deflate the balloon.
• What happens to the paper box?
• What is this similar to in the plant cell?

55
What is the vacuole?

• 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.

56
(No Transcript)
57
Explore a plant cell model

• A plant is made of many plant cells.
• When the vacuoles are full of water, they apply
  force against the cell wallkeeping the plant
  upright.

58
Explore a plant cell model

• 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.

59
This force is called TURGOR PRESSURE.

Response to stimuli

• How do animals respond to stimuli?
• How do you think plants would respond to stimuli?
  

67
Response 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.

• 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?

71

• Hydrotropism is how plants respond to water,
  roots will grow toward the water

72
