Which of the following statements BEST describes the relationship between photosynthesis and respiration in plants at night?
Photosynthesis and respiration both cease, maintaining a neutral balance of gases.
Photosynthesis continues at a reduced rate, while respiration increases to compensate.
Photosynthesis ceases, and respiration also ceases to conserve energy.
Photosynthesis ceases, and respiration continues, consuming stored organic molecules and releasing CO2.
How do plants obtain the oxygen required for respiration at night when photosynthesis is not occurring?
They store oxygen produced during the day
They switch to anaerobic respiration
Through lenticels and diffusion from air spaces within the plant
They do not respire at night
The compensation point in plants is reached when...
Photosynthesis ceases entirely, and only respiration occurs.
The rate of photosynthesis equals the rate of respiration, resulting in no net gas exchange.
Respiration ceases entirely, and only photosynthesis occurs.
The plant switches from C3 to CAM photosynthesis.
