b. ______________
c. _______________
2 The source of carbon for photosynthesis is (a) sun, (b) water, (c) soil, (d) air, (e)
sugars, (f) none of these, (g) all of these.
3 The source of carbon for respiration is (a) sun, (b) water, (c) soil, (d) air, (e) sugars, (f)
none of these, (g) all of these.
4 Photosynthesis can occur in the dark as well as the light. True or false? Explain.
5 At the light compensation point , the rate of photosynthesis equals the rate of
respiration. True or false? Explain.
6 If the rate of photosynthesis exceeds the rate of respiration, the excess photosynthate
can be stored in the plant’s (a) leaves, (b) roots, (c) stems, (d) tubers, (e) all of these, (f)
none of these.
7 The energy from photosynthesis can be stored in the form of (a) sugars, (b) starches,
(c) proteins, (d) all of these, (e) none of these.
8 If respiration exceeds photosynthesis (a) the plant is growing, (b) the plant is not
growing. Explain.
9 When a plant is photosynthesizing, it gives off oxygen gas. The oxygen comes from
(a) water, (b) air, (c) CO2, (d) sugar, (e) starch, (f) all of these, (g) none of these.
10 Where does the hydrogen for the NADP+ come from?
11 Carbon is (a) oxidized, (b) reduced during photosynthesis.
12 Carbon is (a) oxidized, (b) reduced during respiration.
13 The product of the anaerobic phase of glycolsis in plants is (a) sugar, (b) starch, (c)
ethyl alcohol, (d) pyruvic acid, (e) ATP, (f) NADP.
14 The source of all energy on earth is the sun. True or false? Explain.
15 Relative to aerobic glycolysis there is (a) no, (b) some, (c) much energy produced
during the anaerobic phase of glycolsis.
16 What is left when hydrogen is removed from the water molecule? What eventually
happens to the remaining part of the water molecule?
17 What is the ultimate fate of hydrogen that is passed along the hydrogen transport
system in respiration?
18 What percentage of the sun’s energy is fixed by plants?
19 What does light saturated mean in reference to photosynthesis?
20 What happens if respiration exceeds photosynthesis? Explain.
