1 Plants Produce Food

2 Every organism on Earth needs energy to live and grow.

3 The primary source of all life energy on Earth’s is the Sun.

4 But animals can’t eat sunlight.

5 Animals can only get energy by eating (consuming) other organisms (plants or animals).

6 Animals are consumers.

8

9 Animals must eat (consume) to get the energy they need.

10

11 Animals are consumers.

12 Animals must eat food (consume) to get the energy to live.

13 Only green plants can produce food. Plants Plants are producers. Produce means “to make.” Producers make food from sunlight energy.

14 Plants make food from sunlight. Plants are producers. Produce means “to make.” Producers make food from sunlight energy.

15 But there is one type of organism that can produce food from sunlight energy. Plants Plants are producers. Produce means “to make.” Producers make food from sunlight energy. Plants are producers.

16 But there is one type of organism that can produce food from sunlight energy. Plants Plants are producers. Produce means “to make.” Producers make food from sunlight energy. Plants are producers. Produce means “to make.”

17 Producers make food from sunlight energy.

18 Plants are producers. They make food. Only plants can make food.

19 Plants make food in their leaves.

20 A green material in leaves called chlorophyll (klor oh fil) turns light energy from the sun into chemical energy (sugar).

21 Producers convert sunlight energy into a chemical energy (glucose; sugar; food) that animals must have to live.

22 Sugar made in the leaves moves through tubes to other parts of the plant..

23 Plants store the food they make in different ways.

24

25

26 Plant leaves must have three things in order to make food.

27 Plants must have three things in order to make food. light

28 Plants must have in order to make food. water

29 Plants must have in order to make food. carbon dioxide

30 CO 2 (carbon dioxide) is a gas that makes up about 1% of Earth’s atmosphere.

31 Plants must have three things in order to make food. light water also called H 2 O Carbon dioxide a.k.a. CO 2

32 Plants must have three things in order to make food. light water also called H 2 O Carbon dioxide CO 2

33 Plants must have three things in order to make food.light CO 2 Carbon dioxide H2OH2O water

34 Plants get the light they need from the Sun. sun

35 Plants get the CO 2, carbon dioxide, they need from the air.

36 Plants get the water they need from soil with their roots.

37 Water goes through tubes in the stem to get to the leaves.

38 The process of plants turning sunlight energy, CO 2, and water into chemical energy (food, sugar) is called …

39 photosynthesis (foh toh SIN theh sis)

40 The process of plants turning sunlight energy, CO 2, and water into chemical energy (food, sugar) is called photosynthesis (foh toh sin theh sis)

41 photosynthesis Photo means “light”

42 photosynthesis Photo means “light” synthesis mean “to put together”

43 photosynthesis Photo means “light.” Synthesis mean “to put together.” Photosynthesis mean “to put it together using light.”

44 photosynthesis Photosynthesis mean “to put together with light.” Photo means “light” synthesis mean “to put together” Plants “put food together” using light energy in the process called photosynthesis.

45 Plants take (CO 2 ) carbon dioxide into their leaves and use it during photosynthesis. CO 2

46 Plants release (throw away) oxygen as a waste product as they make food. oxygen

47 Plants release (throw away) oxygen as a waste product as they make food. Oxygen is a gas that makes up 21% of the air.

48 Plants can’t live without CO 2 and must release oxygen.

49 Animals can’t live without oxygen and must release CO 2.

50 This is a very important balance for life on Earth.

51 Now, let’s see how much you remember about producers and photosynthesis.

52 Which type of organisms must eat other organisms?

53 Consumers (animals) must eat other organisms.

54 Which type of organisms can make food?

55 Only producers (plants) can make food.

56 ? What waste gas is released by plants as they make food?

57 oxygen Oxygen is the waste gas released by plants as they make food.

58 Review: What waste gas is released by animals as they live and breathe?

59 Review: CO 2 carbon dioxide is the waste gas released by animals as they live and breathe. CO 2

60 What gas is needed by plants as they make food? ?

61 CO 2 gas is needed by plants as they make food. CO 2 Carbon dioxide

62 Review: What is the name of the process in which plants (producers) make food?

63 Photosynthesis is the process in which plants make food.

64 Review: In what part of the plant is sunlight turned into food? (glucose; sugar)

65 Leaves are the part of the plant where food is made during photosynthesis. One leaf Three leaves

66 What is the name for the energy chemical that plants and animals need to live and grow?

67 Hint: Plants make it in their leaves from sunlight, CO2 and water.

68 Sugar or glucose is the name for the energy chemical that plants and animals need to live and grow.

69 What is the name of the green substance that converts sunlight energy to make sugar in the leaves of plants?

70 Chlorophyll is the green substance that converts light into sugar in the leaves of plants.

71 light CO 2 Carbon dioxide H2OH2O water What three things do plants need in order to make food during photosynthesis? 1 3 2

72 light CO 2 Carbon dioxide H2OH2O water Plants must have these three things in order to make food in photosynthesis.

73 What two things do plants produce during photosynthesis?

74 Sugar and oxygen are produced by plants during photosynthesis. Oxygen O 2 Sugar glucose

75 Review: What is another way to say carbon dioxide?

76 Review: What is another way to say carbon dioxide? CO 2

77 Review: What is another way to say water?

78 Review: What is another way to say water? H2OH2O

79 Photosynthesis sunlight CO 2 H2OH2O Carbon dioxide water

80 Photosynthesis sunlight CO 2 H2OH2O Carbon dioxide water oxygen

81 Photosynthesis sunlight CO 2 H2OH2O Carbon dioxide water oxygen sugar

82 Plants move materials through a system of tubes.

83 Xylem (zy lem) tubes carry water and nutrients from roots to the leaves.

84 Phloem (FLO em) are the tubes that carry sap (sugar and water) from leaves to every part of the plant.

85 Organisms have system of tubes to transport materials. Plants have xylem and phloem tubes.

86 Organisms have system of tubes to transport materials. Animals have blood vessels.

87 system of tubes Organisms have a
