How are cellular respiration and photosynthesis related, in terms of energy?
a) The energy captured in photosynthesis is used to power cellular respiration.
b) The energy transformed in cellular respiration is used to power photosynthesis.
c) Photosynthesis and respiration perform the same task in terms of energy transformation.
d) Energy is not involved in either photosynthesis or cellular respiration.
In which way are photosynthesis and cellular respiration different?
a) Cellular respiration stores ATP, while photosynthesis releases ATP.
b) Cellular respiration produces oxygen, while photosynthesis uses oxygen
c) Photosynthesis releases energy, while cellular respiration stores energy.
d) Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.
A potted plant is placed inside a clear, sealed vacuum container that has water pumped into it on a regular basis. The container is placed in the sun and the plant’s growth is monitored. Which statement best describes what will most likely happen to
a) The plant will grow faster because it is sheltered from the wind.
b) The plant will die because it does not have oxygen for photosynthesis.
c) The plant will die because it does not have carbon dioxide for photosynthesis
d) The plant will grow at a slower rate because it requires more water.
