Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1.What does a plant need to survive and grow? H2O, CO2, Sun.
2.What does an animal need to survive and grow? Food, water as well as oxygen.
3.How do animals and plants depend on each other? Plants are able to provide oxygen
and food in order for animals to survive and they depend on each other in this way.
Plants can also be a form of shelter for animals. Animals can sometimes provide
plants with water and with carbon dioxide.
Gizmo Warm-up
The Cell Energy Cycle Gizmo™ illustrates two
processes that are essential to life: photosynthesis
and cellular respiration.
Although both of these processes involve a series of
complex steps, the inputs and outputs of each process
are four relatively simple molecules.
1.What is the chemical formula of oxygen? O2
2.Glucose is a simple sugar. What is the chemical
formula of glucose? C6H12O6
3.What is the chemical formula of carbon dioxide? CO2
4.What is the chemical formula of water? H2O

Solution:
The photosynthesis process creates products that are used up as starting molecules in the cellular respiration process. This way the gases (oxygen and carbon dioxide) are exchanged between the environment and the living organisms. The photosynthesis process uses light energy or sunlight to convert the cellular respiration products or outputs (water and carbon dioxide) into glucose (chemical energy) and oxygen. These photosynthesis products (glucose and oxygen) are used up as starting molecules for cellular respiration. The oxygen molecules are used to convert the glucose molecules into water, energy molecules (ATP - adenosine triphosphate), and carbon dioxide via the cellular respiration process.
