Question :Two green plants are kept separately in oxygen-free containers, one in the dark and the other in sunlight. It was observed that plants kept in dark could not
survive longer. Give a reason for this observation.

The correct answer is -Plants undergo a process called photosynthesis, which involves the conversion of light energy into chemical energy in the presence of chlorophyll. During photosynthesis, plants produce oxygen as a by-product, which they release into the environment. In an oxygen-free environment, plants cannot carry out photosynthesis, and as a result, they are unable to produce oxygen, which is essential for their survival.

The plant kept in sunlight is able to survive longer than the plant kept in the dark, as it can carry out photosynthesis due to the presence of light, and thus produce oxygen. However, the plant kept in the dark cannot carry out photosynthesis and hence, cannot produce oxygen. As a result, it cannot survive for long in an oxygen-free environment.
