Photosynthesis is the process by which plants transform solar energy into chemical energy. Which of the following
correctly describes the roles of each of the materials involved in photosynthesis; after sunlight is captured by chlorophyll? (SC.8. L.18.1)
Sunlight combines with glucose and oxygen molecules and creates carbon dioxide. Remaining atoms form oxygen and water, which are released as waste products.
Sunlight combines with carbon dioxide and water molecules and creates glucose. Remaining atoms form Oxygen which is released as waste product. (byproduct)
Sunlight combines oxygen and water molecules and creates glucose. Remaining atoms form carbon dioxide and water, which are released as waste products.
Sunlight combines water and carbon dioxide molecules and creates glucose. Remaining atoms form carbon dioxide and water, which are released as waste products.

- 9. Multiple Choice
Jamie is running a race this afternoon. He eats breakfast to make sure that he can reach the finish line because food provides the energy his cells need to complete any activity. What kind of energy is stored in food? (SC.8. L.18.1)
Chemical Energy
Kinetic Energy
Light Energy
Mechanical Energy
- 10. Multiple Choice
A student conducted a science experiment about how light impacts plant growth. He placed one plant in full sunlight all day, one with sunlight half of the day and one in a closet with no sunlight. The student then recorded their growth over a 5-week period. His data is listed in the data table below.
Which data analysis statement BEST describes the connection between sunlight and photosynthesis that this data table represents? (SC.8. L.18.1)
The plant in the dark closet stopped growing because the plant uses sunlight to create the particles of food energy the plant needs to grow.
The plant in the dark closet grew at the same speed as a plant in sunlight because all plants are given the same amounts of water and carbon dioxide.
The plant in the dark closet grew slower than a plant in sunlight because the dark plant would have had to pull more energy from water and carbon dioxide.
The plant in the dark closet grew faster than a plant in sunlight because processing the energy from the sun used part of the food energy the plant needed to grow.
- 11. Multiple Choice

All the above
- 12. Multiple Choice
During cellular respiration, energy is captured from the food that we eat and stored in our bodies for future use. Which of the following is NOT a product of cellular respiration? (SC.8. L.18.2)
Carbon Dioxide
Water
Oxygen
Adenosine Triphosphate (ATP)
- 13. Multiple Choice

- 16. Multiple Choice
Given the following images, what does each picture represent and how can they be arranged to accurately represent the photosynthesis and cellular respiration cycles? (SC.8. L.18.2)
The soccer player needs energy to kick the ball. He gets that energy by eating the plant. He combines the glucose from the plant with carbon dioxide to release energy during cellular respiration. His body releases oxygen during this process. The plant uses carbon dioxide, water and sunlight to make new glucose during photosynthesis.
The soccer player needs energy to kick the ball. He gets that energy by eating the plant. Once he has eaten the plant, his body gets energy from the glucose in the food. His body releases carbon dioxide and oxygen through this cellular respiration. The plant uses the sunlight, oxygen, and carbon dioxide to make new glucose during photosynthesis.
The sun represents the light energy needed to begin photosynthesis. The plant is taking in the sun’s energy, using water and carbon dioxide to make glucose. The soccer player eats the plant to get glucose and breathes in the oxygen. Through cellular respiration, he uses the oxygen to break down the glucose to obtain the energy needed to kick the ball. He breathes out carbon dioxide and sweats out water.

- 20. Multiple Choice
Sarah believes that only animals undergo cellular respiration. Drew believes that both plants and animals undergo cellular respiration. Only one student is correct. Which answer choice BEST explains why? (SC.8. L.18.2)
Drew is correct because both plants and animal cells need chemical energy to carry out cellular processes.
Sarah is correct because plant cells do not need chemical energy for cellular processes and animal cells do.
Drew is correct because plants need to store more chemical energy and animals need chemical energy for cellular processes.
Sarah is correct be plant cells already have chemical energy stored in them and animal cells need chemical energy for cellular processes.
