Planting Seeds!
  • 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 dont 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.

Planting Seeds
  • Now zip shut the bag.
  • Tape your bag to the window, near your period
    sign.

Plant Poster Expectations
  • Draw a plant.
  • Label major organs and organ systems.
  • Include the function of each organ.
  • Include basic needs of plants (draw and label
    them)
  • Draw a plant cell and label its 7 organelles.

27
Do First 11.8
  • Person number 3 will go to the window and observe
    their plant.
  • Label the parts of the plant and then answer
    these questions on the back.
  • 1. What are the major organs of a plant?
  • 2. What is the function of the leaf?

28
What is this?
A Seedling
Shoots
Roots
29
SEEDS!
  • Using page 331, read about seeds. As you are
    reading, complete your chart on seeds.
  • Answer these questions as well
  • What are the three parts of a seed?
  • How do seeds sprout?

30
How does a seed become a seedling?
  • http//plantsinmotion.bio.indiana.edu/plantmotion/
    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.

36
From seed to plant.
37
Exit Ticket
  • Name a force that helps seeds become seedlings.

38
Do First 11.9
  • 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?

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?

47
Do First 11.11
  • 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.

48
Hmmmm
  • 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.

49
This is what they look like
50
Do First 11.12
  • 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?

51
Why does this happen to a plant?
52
Lets Remember
  • 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.
60
This is what is it looks like
  • http//www.kscience.co.uk/animations/turgor.htm

61
Exit Ticket
  • 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?
  • Described WILTING.

62
Tracking quiz 1
  • Track levels of organization on levels of org
    quiz 1
  • Track seeds to seedlings on forces quiz 1
  • Set goals for levels of org quiz 2 and forces
    quiz 2

63
Remembering from unit 2
  • What is a stimuli?
  • A change in the environment
  • What is a response?
  • An organisms reaction to that change
  • Why must organisms respond to stimuli?
  • To maintain homeostasis or keep the organism
    healthy

64
Response to stimuli
Do plants respond to stimuli or changes in their
environment? What are some examples you can
think of?
Do plants respond to stimuli or changes in their
environment? What are some examples you can
think of?
  • Do plants respond to stimuli or changes in their
    environment?
  • What are some examples you can think of?

65
What is this plant responding to?
  • http//214bio.com/SWF/auxin_phototropism.swf

66
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.

68
Response to touch
  • 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-plant
    s-climb-trees.html
  • How does the vine respond to touch?
  • How does the Venus fly trap respond to touch?

69
Morning Glory Vine
70
Response to light
  • 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
Response to water
  • Hydrotropism is how plants respond to water,
    roots will grow toward the water

72
Response to gravity
  • How do plants respond to gravity?
  • Shoots grow upward and roots grow downward
  • What is this response called?
  • GEOTROPISM

73
Tropism game show!
  • A plants roots grow toward the water.
  • 2.
  • 3. A plants leaves curl up when touched.
  • 4.

74
Exit Ticket
  1. Name four stimuli that plants respond to.
  2. What is a tropism?
