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?
Explanation / Answer
Answer:
(a) The plant will die since it will not be able to synthesize glucose through Calvin cycle due to absence of CO2.
(b) The mouse will die since it will not be able to perform aerobic respiration in the absence of O2.
(c) In this case, the plant will produce O2 through light reaction which can be utilized by the mouse for carrying out respiration. The mouse on the otherhand will exhale CO2 which will be utilized by the plant for dark reaction.
So, both the plant and the mouse can survivee (live) atleast for sometime.
