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.

Explanation:

Plants do not live without sun. Plants with the help of sun energy and nutrient absorption from the soil produce their own food. This process that the plant performs is called photosynthesis and is totally dependent on sunlight. For this reason, we can conclude that in the case of the above question, the seedling kept in the sunlight survives because it can synthesize its own food. The seedling in the oxygen chamber dies because it receives no carbon dioxide and is unable to synthesize its own foods.
