Chapter 8 Photosynthesis Review

Review Rules Answers must be discussed by all members of group (max of 3) and a consensus answer acquired Correct answers must remain visible until correct answer has been scored Team that received the most points will win 5 points extra credit on their quizzes These notes are online-focus on answers and discussion

Question 1 Where are the Pigments, or light collecting units of photosynthesis found? Thylakoid Membrane Stroma Chloroplast Membrane Answer- a) Thylakoid Membrane

Question 2 Which of the following is an autotroph A)Dog B)Tree C)Mushroom D) Mr. Morales Answer- B) Tree- Organisms that produce their own food are autotrophs

Question 3 Which of the following are used in the overall reactions for photosynthesis? A) Carbon dioxide B) Water C) Light D) All of the above Answer- D) all of the above

Question 4 What does the Calvin cycle need from the light dependant reactions? a) ATP b) NADPH & ATP c) NADP+ d) NADP+ & ATP Answer- b) NADPH & ATP

Question 5 ________ are stacked up on top of each other to compose granum Answer- Thylakoids-

Question 6 Most plants appear green because chlorophyll a) Does not absorb green light b) Reflects violet light c) Absorbs Green light d) None of the above Answer A) Does not absorb green light

Question 7 What are the green Structures in these plant cells Answer- Chloroplasts

Question 8 What is the product of light-Dependent reactions? Answer- ATP or Oxygen or NADPH

Question 9 If carbon dioxide is removed from a plant’s environment, what would you expect to happen to its production of energy sugars? More sugars will be produced No Sugars will be produced Carbon Dioxide does not affect the production of high energy sugars in plants Answer- B) No sugars will be produced (carbon dioxide needs to be fixed to produce sugar in the Calvin cycle)

Question 10 If you continue to increase the intensity of light that a plant receives, what happens? The rate of photosynthesis increases with light intensity The rate of photosynthesis decreases with light intensity The rate of photosynthesis increases and then levels off. The rate of photosynthesis does not change Answer C) The rate of photosynthesis increases and then levels off (Too much light and the enzymes begin to denature and photosynthesis levels off)

Question 11 What effects photosynthetic rates? Amount of carbon dioxide Amount of light Temperature All of the above Answer- D) All of the above

Question 12 Something that collects light is called a a) Chloroplast b) Pigment c) Thylakoid d) Grana Answer- b) Pigment ( Pigments are the part of the thylakoid that collects the light)

Question 13 What is missing from the photosynthetic equation Answer Water or 6H20

Question 14 The Calvin cycle is another name for Light-independent reactions Light-dependant reactions Photosynthesis Answer- A) Light-independent Reactions( Doesn’t depend on light)

Question 15 Energy release from converting ATP to ________ is commonly used for active transport, protein synthesis and muscle contraction Answer- ADP

Question 16 This picture is depicting the Calvin Cycle, Study the picture and write what the product is. Answer- C6H12O6

Question 17 The stroma is the space that surrounds a)Thylakoids b) Chloroplasts c) Plant Cells Answer- A) Thylakoids (Stroma is the fluid in the chloroplasts)

Question 18 What is the waste product of Photosynthesis Answer- Oxygen

Question 19 Standard:Students know usable energy is captured from _________by chloroplasts and is stored through the synthesis of ___________ from carbon dioxide. Answer- Sunlight, Sugar

Question 20 Last Question ________ is the carrier of electrons in a process called Electron Transport Answer- NADPH

Summary Photosynthesis is the action of converting light energy into chemical energy Plants need Carbon dioxide, water and sunlight to make oxygen and sugar Photosynthesis makes ATP from sunlight which is needed by the Calvin cycle to make SUGAR I LOVE MR M
