earlygrowth/germination/germ.html
31What is a seed?
- A seed contains a baby plant, stored up energy,
and a protective seed coat.
32What do seeds need?
- Seeds need water to sprout or grow.
-
- Once the seed receives water, it awakens or
germinates,
33What happens next?
- The seeds absorb so much water, that the force
of the water pressure pushes open the seed.
34Another way to say it..,
- The dry seed absorbs water, the plant cells get
bigger and the plant breaks out of the seed.
35Another 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.
36From seed to plant.
37Exit Ticket
- Name a force that helps seeds become seedlings.
38Do 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?
39Big Question
- What would happen if a seedling got turned
around? - Would the roots grow up and the shoots grow
downward?
40This is what happens
41Describe the seedlings in your notes.
Shoot
root
42Why does this happen?
- http//plantsinmotion.bio.indiana.edu/plantmotion/
movements/tropism/tropisms.html
43Why does this happen?
- Plants are able to sense gravity and respond to
changes in position. - This response is called geotropism.
44Why 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.
45Not just for seedlings.
- Grown plants also respond to geotropism.
- Their roots will grow downward and their shoots
will grow upward.
46Thinking 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?
47Do 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.
48Hmmmm
- 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.
49This is what they look like
50Do 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?
51Why does this happen to a plant?
52Lets Remember
Cell Wall
Vacuole
53Explore 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?
54Explore a plant cell model
- Now deflate the balloon.
- What happens to the paper box?
- What is this similar to in the plant cell?
55What 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)
57Explore 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.
58Explore 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.
59This force is called TURGOR PRESSURE.
60This is what is it looks like

66Response to stimuli
- How do animals respond to stimuli?
- How do you think plants would respond to stimuli?
67Response 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.
68Response 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?

69Morning Glory Vine
70Response 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?
71Response to water
- Hydrotropism is how plants respond to water,
roots will grow toward the water
72Response to gravity
- How do plants respond to gravity?
- Shoots grow upward and roots grow downward
- What is this response called?
