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.

    They are related also because they are dependent on each other. The product of photosynthesis i.e., glucose (food) is utilised in respiration to yield energy (ATP). Which doing so, it releases many other simple molecules (CO2+H2O) which are utilised in photosynthesis to produce more sugers.
    The end product of Photosynthesis is glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
    The products and reactants for photosynthesis are reversed in cellular respiration: The reactants of photosynthesis are carbon dioxide and water, which are the products of cellular respiration. The reactants of cellular respiration are oxygen and sugar, which are the products of photosynthesis.

    How are photosynthesis and cellular respiration dependent on each other?

    Photosynthesis and cellular respiration are dependent on each other as the products of each of these reactions initiate the other reaction. The sugar molecules or glucose molecules produced in the reaction of photosynthesis are used as reactant molecules in the respiration reaction.
