Name Date Cellular Respiration Virtual Lab Carbon Transfer Through Snails and Elodea Period Background: All organisms are dependent on a healthy carbon dioxide-oxygen balance. Photosynthesis and cellular respiration are key processes in maintaining this balance. Plants, through the process of photosynthesis, use energy absorbed from sunlight, water, and carbon dioxide to produce sugars and oxygen. Animals and plants, through the process of cellular respiration, use oxygen and sugars to produce carbon dioxide, water, and the energy needed to maintain life. Purpose: To determine how carbon dioxide cycles through a biological system by performing the "Carbon Transfer Through Snails and Elodea" virtual experiment found on this webpage: http://www.classzone.com/cz/books/bio 07/resources/htmls/virtual labs/virtuallabs.html Procedure: Follow the steps to the lab given on the screen until you complete all seven (7) steps. You will need to fill in the lab notebook as you go, but you will only be graded on what you put on this assignment sheet. 1. Read through the problem tab. Create your own question for what you are investigating in this experiment. a. Problem (in question form): 2. Explore the lab to learn what is available to you in your investigation. You must click on each item in the checklist. Describe the materials you will be using in this lab. a. What is Bromthymol Blue? Why is the BTB in the beaker green? b. If snails use lungs to breathe, you can conclude that they release which gas into their environment as a result of respiration? d. What is the purpose of the growth light? c. If Elodea is an aquatic plant, you can conclude that it releases which gas into its environment as a result of photosynthesis? e. What is the purpose of the test tube rack cover?
