The plant kept in continuous light will live longer. This is because it can perform photosynthesis and produce its own oxygen, which is crucial for respiration. The plant in the dark cannot photosynthesize and will quickly deplete its oxygen supply, leading to a faster death.
Explanation:
Photosynthesis:
Plants use sunlight, water, and carbon dioxide to produce glucose (food) and oxygen.
Respiration:
All living organisms, including plants, require oxygen for respiration to convert food into energy.
Oxygen Production:
The plant in the light produces oxygen through photosynthesis, replenishing the oxygen needed for respiration.
Oxygen Depletion:
The plant in the dark cannot photosynthesize and will run out of oxygen faster, as it uses it for respiration but doesn’t produce it.
