Question

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

Answer 1

When two green plants are placed in separate oxygen-free containers, the one exposed to continuous light survives longer because it can carry out photosynthesis. This process releases oxygen into the container, which the plant then utilizes to perform cellular respiration for its energy needs.
