1. Plants LS4 3.08

2. Plants are organisms.

3. Plants are the type of organism that can produce their own food, unlike animals. Animals must consume other organisms for the energy they need.

4. Plants produce food energy in a process called photosynthesis.

5. Three things are needed by plants in order for photosynthesis to occur.

6. Light from the Sun

7. Light from the Sun CO 2 from the air

8. Light from the Sun CO 2 from the air Water from the plants roots

9. Notes:

10. What is the process called in which plants make food? Notes:

11. What is the process called in which plants make food? Photosynthesis Notes:

12. What three things must plants have in order to make food? Notes:

13. What three things must plants have in order to make food? Notes: Light CO 2 water

15. Plants need small amounts of other substances (vitamins, minerals) to do their best work. Plants get these nutrients from the soil.

16. What do we call the small amounts of vitamins and minerals that plants get from the soil? Notes:

17. What do we call the small amounts of vitamins and minerals that plants get from the soil? Notes: Nutrients

19. Plants don’t live forever. They grow old and die like every other organism.

20. Plants would disappear from Earth unless they reproduce. “Reproduce” means to make more of the same.

21. The way most plants reproduce is by making seeds .

22. But, before a plant can make a seed, it must get a tiny bit of pollen from a similar plant. This pollen is magnified many times

23. Pollen is made in a plant’s flower. Pollen is a fine powder that can blow on the breezes from one plant to another.

24. But blowing in the wind is not a sure way to get pollen from one plant to another.

25. Sometimes animals help plants move pollen from plant to plant. Plants make nectar, a sweet substance, in their flowers.

26. Pollen sticks to animals as they collect nectar. Some pollen falls off at the next flower. It just takes a tiny bit of pollen for a plant to make a seed.

28. How do most plants reproduce (make new plants like themselves)? Notes:

30. What must most plants do before they can make seeds? Notes:

31. What must most plants do before they can make seeds? Notes: Get pollen from a similar plant

32. What are two ways that pollen gets from one plant to another? Notes:

35. What is the most important animal for pollination of plants? Notes:

36. What is the most important animal for pollination of plants? Notes: Bees

37. After pollination has taken place, the plants can make seeds.

38. A seed contains a baby plant together with a supply of food to get it started. Ungerminated plant Plant food seed

39. After it germinates, the new plant must reach the sun for energy before the food in the seed runs out.

40. Some plants produce seeds in ways that make food for animals.

41. Once again animals can help the plants.

42. Once again animals can help the plants. This time, by dispersing seeds so new plants can grow in different areas.

43. Animals drop some seeds as they move around. Animals help plants by dispersing seeds.

45. What is another way that animals help plants? Notes:

46. What is another way that animals help plants? Dispersing seeds Notes:

47. What does the word “disperse” mean? Notes: To spread around in different places.

49. A seed can stay dormant (asleep) for years. They usually won’t wake up unless there is water.

50. The word for a seed “waking up” and beginning to grow is germination.

51. Germination is also called sprouting.

52. After the seed germinates, the stem grows up and the roots grow down.

53. Some plants send down one strong, deep root called a taproot.

54. Other plants have a system of many softer roots called fibrous roots.

55. Here are plants with a taproot and a fibrous root side by side. taproot fibrous root

57. Other plants have structures that store a lot of food energy in their roots. These roots are called tubers.

93. What is the word for a change that an organism makes to help in live in its environment? Notes:

94. What is the word for a change that an organism makes to help in live in its environment? Notes: adaptation

95. Trees in different climates have to adapt to their local conditions.

96. In a tropical rainforest, near the equator, it is always hot and it rains almost every day. Many plants thrive here.

97. Trees may adapt here by growing very high to catch more sunlight.

98. Plants that don’t grow high need to adapt with large leaves to catch more of the limited sunlight that makes it down low.

101. Deciduous forest dee sid jew us Temperate climates are hot in the summer.

102. Deciduous forest dee sid jew us But they can be very cold in the winter.

103. Deciduous trees adapt to hot summers and cold by having lots of leaves in summer, dropping them all in autumn, and hibernating all winter. summer winter

109. No trees can adapt to grow in ground that is always frozen. In the tundra , in the far north and south latitudes, there are no trees.
