1. Plants for Food and Fibre How do we produce useful plant products and how do we apply these techniques in a sustainable way?

2. Plants and their Uses Brainstorm what you know about plants Create a title page for this unit Bill Nye Plants video… YDNHTWTD

3. Anticipation Guide This is an Anticipation Guide that is used to help you read information from a textbook and understand its meaning. You will be directed to read the following True/False questions. You will write down a “guess” in the Before space. You may not know why your answer is true and false but be ready to defend your reason. ALWAYS HAVE A REASON! This is hard. But we will practice coming up with reasons for your answers. It is a skill to be able to apply what you know to what you don’t know. After you have made your guesses, then you will read that section of the textbook. As you read, you will fill in the After space answer. Again, you should write down your reason for your answer. These questions will serve as your notes for this information. YDNHTWTD

4. p92 Plants are only used to eat. False – clothing, paper, building materials, medicine, oxygen, filters to clean the environment

5. p92 Fibre from plants is only used to make clothing and paper. False – building materials and medicine

6. p92 Plant fibre comes from the stem, leaves seeds, or roots of a plant. True – except sometimes the flowers or seeds can be used for fibre as well.

7. p92 Plants produce carbon dioxide needed for breathing. False – plants produce oxygen needed for breathing and use carbon dioxide to make glucose

8. p92 Cars and factories add carbon dioxide to the air. True – so do humans and animals

9. p92 It takes three large trees to absorb the excess carbon dioxide put into the atmosphere when a car is driven for one hour. False – it takes four trees

10. p92 Plants are the basis of food webs, help clean and filter water, prevent flooding and help keep soil in place. True

11. p92 75% of the world’s food supply is based on seven major crops. True – wheat, rice, barley, maize (corn), potatoes, cassava and sorghum

27. p94 Most of our clothing comes from synthetic material such as cotton, hemp or flax. YDNHTWTD

28. Plants for Fibre First of all, cotton, hemp and flax are natural NOT synthetic fibres. So this statement is false for that. CottonHemp Flax

29. Plants for Fibre However, most of our clothing DOES come from synthetic material like polyester or nylon so it is true for that.

30. p94 Cotton is the world’s most important non-edible plant because it absorbs moisture and allows it to evaporate easily. True YDNHTWTD

31. Cotton The flowers of the cotton plant bloom in the afternoon and after only a few weeks, you can see cotton inside! YDNHTWTD

32. Cotton False – it flowers in the morning and it takes four months to see the cotton inside

33. p95 Hemp is the oldest fibre plant in the world and is used to make jeans. YDNHTWTD

34. Hemp Trulse – Hemp is the oldest fibre and it used to be used to make blue jeans but it isn’t today.

35. Hemp Hemp is better for the environment. YDNHTWTD

36. Hemp True – if we are comparing it to other sources of fibre

37. Hemp True – if we are comparing it to other sources of fibre Ready to harvest in one year

38. Hemp True – if we are comparing it to other sources of fibre Ready to harvest in one year Hemp paper can be recycled more times,

39. Hemp True – if we are comparing it to other sources of fibre Ready to harvest in one year Hemp paper can be recycled more times, Doesn’t need as much pesticides for weeds or insects

40. Flax Flax can be eaten, used for cloth, and also used in paints and disposable diapers. YDNHTWTD

41. Flax True – except for the diaper part – that comes from wood pulp. Some biodegradable diapers are made from sphagnum moss. Reusable diapers are made from cotton.

42. p98 -99 Plants for Medicine Birch resin or sap is used as a natural tooth cleaner for nearly 10 000 years! False – 9000 years YDNHTWTD

43. p98 -99 Plants for Medicine Some pain medications are found naturally in plants and then concentrated in a lab. YDNHTWTD

44. p98 -99 Plants for Medicine True – some pain medication cannot be made artificially like morphine found in opium poppy seeds

45. p98 -99 Plants for Medicine Malaria parasites have developed a resistance to natural quinine. YDNHTWTD

46. p98 -99 Plants for Medicine False – the parasites have developed resistance to the artificial quinine but not the natural quinine from cinchona trees

47. p100-101 Plants for Transportation and Construction Rubber only comes from latex tapped from rubber trees. YDNHTWTD

48. p100-101 Plants for Transportation and Construction Trulse – synthetic rubber can be made from coal and oil by-products, but natural rubber is still an important part

49. p100-101 Plants for Transportation and Construction 90% of all houses are made from wood. YDNHTWTD

50. p100-101 Plants for Transportation and Construction True – mostly from softwood trees such as conifers ie. fir, pine

51. p100-101 Plants for Transportation and Construction Plants are the major source of fuel for warmth and our engines in cars for example. YDNHTWTD

52. p100-101 Plants for Transportation and Construction True – wood, as well as fossil fuels which used to be plants millions of years ago -Producing fuel from plants is economical but not very energy efficient. -A large amount of energy is required to grow and harvest the crop

53. Plants for Food and Fibre How do we produce useful plant products and how do we apply these techniques in a sustainable way?
