Photosynthesis and Cellular Respiration Pre/Post-Test

Score _____/100

Standards Assessed:

SC.6.L.14.3 ? Recognize and explore how cells of all organisms undergo similar processes to

maintain homeostasis, including extracting energy from food, getting rid of waste and

reproducing.

SC.8.L.18.1 ? Describe and investigate the process of photosynthesis, such as the roles of light,

carbon dioxide, water and chlorophyll; production of food and release of oxygen.

SC.8.L.18.2 ? Describe and investigate how cellular respiration breaks down food to provide

energy and releases carbon dioxide.

Explains relationship

Correctly identifies all 4 products (2 from photosynthesis / 2 from cellular respiration)

Correctly identifies all 4 of the 4 reactants from photosynthesis and cellular respiration Accurately identifies both the reactants of photosynthesis are released/created as products of cellular respiration AND both of the reactants used in cellular respiration are the products created/released from photosynthesis

Correctly identifies 3 of the 4 products from photosynthesis and cellular respiration Correctly identifies 3 of the 4 reactants from photosynthesis and cellular respiration Addresses the fact that at least one of the products of photosynthesis is used in the process or cellular respiration AND at least one of the products cellular respiration is used during photosynthesis.

Correctly identifies 2 of the 4 products from photosynthesis and cellular respiration Correctly identifies 2 of the 4 reactants from photosynthesis and cellular respiration Addresses the fact that at least one of the products of photosynthesis is used in the process or cellular respiration OR at least one of the products cellular respiration is used during photosynthesis.

Correctly identifies only 1 of the 4 products from photosynthesis and cellular respiration Correctly identifies 1 of the 4 reactants from photosynthesis and cellular respiration Acknowledges that cellular respiration has a relationship with photosynthesis (and vice versa) but makes no connection between the products of one being used as reactants for the other (vice versa)

No Products identified

No reactants identified

Shows no relationship between the reactants of photosynthesis and products of cellular respiration AND reactants of cellular respiration and products of photosynthesis
