Did you feel prepared for the Free Response?  Multiple Choice: 1.how do you think you did? 2.Was it challenging, easy or just right?  3. Did you feel prepared for the Multiple Choice?  4. Any more questions about Common Assessment?

2 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?

3 Plants Needs Structure Traits

4  What are 4 characteristics of all plants?  Define “autotroph.”  What are the three basic parts of all plants?

5  1. What are characteristics of all plants?  2. What are the needs of plants?  3. Are humans autotrophs?  4. Do plants have organs?

6  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.

7  Now zip shut the bag.  Tape your bag to the window, near your period sign.

8 DateQuantitative Observation (measuring etc) Qualitative Observation (description) 11/3

9 Person number 1 will go to the window and observe their plant. 1. What are the levels of organization? 2. Name an example of a level of organization in the human body. 3. Do plants have organs? 4. Person 1: Please share observations with your table.

10  Observe the plant at your table to determine if plants have organs.

26  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 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?  3. What is the function of the stem?  4. How are xylem and phloem different?

28 Shoots Roots A Seedling

29 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?

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

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

35  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.

36

37  Name a force that helps seeds become seedlings.

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

42 http://plantsinmotion.bio.indiana.edu/plantmo tion/movements/tropism/tropisms.html

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

44  Roots will bend and grow downwards, towards the center of the Earth.Earth  Shoots will bend and grow upwards, or away, from the surface of the Earth.

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

46  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  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  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.

50 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

52  Draw a plant cell…. Vacuole Cell Wall

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

55  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

57  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.

58  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.

61  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  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  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

64  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?

66  How do animals respond to stimuli?  How do you think plants would respond to stimuli?

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

69

70  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  How do plants respond to gravity?  Shoots grow upward and roots grow downward  What is this response called?  GEOTROPISM

73 1. A plants’ roots grow toward the water. 2. 3. A plants’ leaves curl up when touched. 4.

74 1. Name four stimuli that plants respond to. 2. What is a tropism? 3. How do plants respond to stimuli? By moving or growing?
