There are two tomato plantlets. One of them is kept in an oxygen chamber with a light source and another is kept in sunlight. Both of them are watered regularly. What will be the observation after two weeks?
The plantlet kept in sunlight survives as it can synthesize its own food. The plantlet in the oxygen chamber dies as it does not get carbon dioxide and is unable to synthesize its own food.
Both the plantlets survive and grow as they can synthesize their own food.
The plantlet kept in sunlight survives, whereas the other plantlet dies because it received an artificial light source.

The one kept in the oxygen chamber will have its leaves turn yellow as there is no presence of carbon dioxide which is essential for photosynthesis for the production of chlorophyll which gives leaves it green colour. The one kept in sunlight will have green leaves due to presence of carbon dioxide for photosynthesis and thus the production of chlorophyll
