Guard cells cause a stoma to open and close. Photosynthesis and Respiration Photosynthesis takes place in the chloroplasts of plant cells. Light energy is used to produce glucose and oxygen from carbon dioxide and water. Photosynthesis provides the food for most organisms on Earth.

35. To return to the chapter summary click Escape or close this document. 1 1 Reviewing Main Ideas Photosynthesis and Respiration Oxygen is used in the mitochondria to complete respiration in plant cells and many other types of cells. Energy is released and carbon dioxide and water are produced. The energy released by respiration is used for the life processes of most living organisms, including plants. Photosynthesis and respiration are almost the reverse of each other.

36. To return to the chapter summary click Escape or close this document. 2 2 Reviewing Main Ideas Plants respond positively and negatively to stimuli. Plant Responses A stimulus from outside the plant is called a tropism. Outside stimuli include light, gravity, and touch.

37. To return to the chapter summary click Escape or close this document. 2 2 Reviewing Main Ideas Plant Responses The length of darkness each day can affect flowering times of plants. Plant hormones cause responses in plants. Some hormones cause plants to exhibit tropisms. Other hormones cause changes in plant growth rates.

39. To return to the chapter summary click Escape or close this document. Chapter Review A. It contains most of the cells with chloroplasts. B. It is just below the upper epidermis. C. There are no stomata in this layer. D. The cells are neatly arranged. LE 1.1f

40. To return to the chapter summary click Escape or close this document. Chapter Review Answer The correct answer is A. Chloroplasts are where photosynthesis, the process plants use to make food, takes place.

41. To return to the chapter summary click Escape or close this document. Chapter Review Question 2 Plants use light that they absorb as energy for photosynthesis. What does this diagram tell you about the importance of green light for photosynthesis? LE 6.2a

42. To return to the chapter summary click Escape or close this document. Chapter Review Answer Because green light is reflected, it is not an important source of energy for photosynthesis. However, leaves look green because you see reflected light rather than absorbed light.

44. To return to the chapter summary click Escape or close this document. Chapter Review Answer They are the same. Respiration uses glucose and oxygen as raw materials while photosynthesis produces glucose and oxygen. These two processes are almost the reverse of each other.

45. To return to the chapter summary click Escape or close this document. Chapter Review Question 4 Which was first isolated from a fungus disease in rice plants called “foolish seedling” disease? A. abscisic acid B. auxins C. cytokinins D. gibberellins LE 1.2h

46. To return to the chapter summary click Escape or close this document. Chapter Review Answer The correct answer is D. Gibberellins are hormones that cause changes in plant growth. They can be used to stimulate plant stems to grow and seeds to germinate.

47. To return to the chapter summary click Escape or close this document. Chapter Review Question 5 Why is the hormone abscisic acid important to plants that grow in areas with cold winters? Answer This hormone stops seeds from sprouting and buds from developing during the winter. If seeds or buds developed during the winter, they would die. LE 1.2h

Standardized Test Practice Question 1 What is light energy trapped during the light- dependent reactions of photosynthesis used for in the light-independent reactions? A. to combine carbon dioxide and hydrogen B. to combine oxygen and carbon dioxide C. to convert oxygen into water D. to split water into oxygen and hydrogen LE 6.2a

49. To return to the chapter summary click Escape or close this document. Standardized Test Practice Answer The correct answer is A. When carbon dioxide and hydrogen combine during the light independent reactions, sugars are produced. One important sugar produced is glucose.

50. To return to the chapter summary click Escape or close this document. Standardized Test Practice Question 2 What does this diagram represent? LE 6.2a

51. To return to the chapter summary click Escape or close this document. Standardized Test Practice A. photosynthesis in a chloroplast B. photosynthesis in a mitochondrion C. respiration in a chloroplast D. respiration in a mitochondrion LE 6.2a

52. To return to the chapter summary click Escape or close this document. Standardized Test Practice The correct answer is A. This diagram shows the entry of raw materials for photosynthesis into the chloroplast and the exit of the end products of this process. Answer

53. To return to the chapter summary click Escape or close this document. Standardized Test Practice Why do plants use the process represented in this diagram? Question 3 LE 1.2d

54. To return to the chapter summary click Escape or close this document. Standardized Test Practice A. to produce food B. to produce oxygen C. to release energy from food D. to release oxygen from water LE 1.2d

55. To return to the chapter summary click Escape or close this document. Standardized Test Practice The correct answer is C. This diagram shows the process of aerobic respiration that occurs in the mitochondria. Plants use this energy for life processes like transporting sugars and opening and closing stomata. Answer

56. To return to the chapter summary click Escape or close this document. Standardized Test Practice Which is stimulated by the hormone ethylene? Question 4 A. closing stomata B. development of flowers C. growth of lateral branches D. ripening of fruit LE 1.2h

57. To return to the chapter summary click Escape or close this document. Standardized Test Practice The correct answer is D. Ethylene is a gas that is released into the air around plants. It is produced in the cells of ripening fruit. Answer

58. To return to the chapter summary click Escape or close this document. Standardized Test Practice These two circle graphs show the length of day and night at two times of year. Which correctly describes photoperiodism of certain plants? Question 5 LE 4.3

59. To return to the chapter summary click Escape or close this document. Standardized Test Practice A. Day-neutral plants would only flower during late fall. B. Long-day plants would only flower during early summer. LE 4.3

60. To return to the chapter summary click Escape or close this document. Standardized Test Practice C. Long-day plants would only flower during late fall. D. Short-day plants would only flower during early summer. LE 4.3

61. To return to the chapter summary click Escape or close this document. Standardized Test Practice The correct answer is B. Long-day plants require less than 10 to 12 hours of darkness to begin the flowering process. There is too much darkness in the late fall for these plants to flower. Answer
