Two green plants are kept separately in oxygen free containers,

Two green plants are kept separately in oxygen free containers, one in the dark and other in the continuous light. Which one will live longer? Give reasons.

The plant which is kept in the dark is unable to carry out photosynthesis and hence the container would be filled with $CO_{2}$ within a very short span of time. Lack of oxygen in the container would kill the plant. On the other hand, the plant kept in light would be able to carry out photosynthesis and thus convert $CO_{2}$ into oxygen. Hence, this plant would live for a longer duration.
