Question

Predict what will happen in the following experiment based on what you know about photosynthesis and cellular respiration. You place a plant alone in a covered airtight container in the presence of sunlight. Assume a watering system is provided. What will happen to the plant (will it live or die), and why? You place a mouse alone in a covered airtight container with food and a source of water. What will happen to the mouse, and why? You place a plant and a mouse together in a covered airtight container with food, water, and sunlight. What will happen to the plant and the mouse, and why?

Answer 1

For photosyntheis plant requires carbon di oxide, water, sunlight along with all internal cell organalles as well as for repiration plant or animal requires glucose, oxygen and water along with all internal cell organlles.

When the plant is under covered airtight container, plant will die due to lack of CO2 which is required for photosynthesis, in the absence of CO2 plant fails to synthesize its food material, it will die.

When the rat is under  covered airtight container, the rat will die becuase of the absence of Oxygen, oxygen is required for respiration, in the absence of O2 rat fails to do respiration so, it will die.

When the rat and plant under airtight container, the both can survive, because the O2 during photosynthesis will be utilized by rat and the CO2 which liberated from rat respiration will be utilzed by the plant.
