Solution

Plant which is kept in continuous light will live longer. This is because, light which is required by plants to perform photosynthesis is present for them. Photosynthesis is the process which is used by plants to make food and produce oxygen for respiration. The plant which is kept in dark would not be able to live due to lack of oxygen for respiration and light for photosynthesis
