Photosynthesis & Respiration TR

How do organisms get the energy they need?

• Plants get energy from fertilizers and animals get energy from drinking water.
• Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.
• Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms.
• Plants do not require energy because they do not move, and animals get energy by performing exercise.

Which of the following is NOT a necessary input for the process of photosynthesis?

• CO ₂ (carbon dioxide)
• Sunlight
• H ₂O (water)
• O ₂ (oxygen)

Which item listed is NOT produced in the process of cellular respiration?

• CO ₂  (carbon dioxide)
• C₆H₁₂O₆  (glucose)
• H₂O (water)
• Energy in the form of ATP

In what way is photosynthesis and respiration related to each other?

• The reactants of photosynthesis are the reactants of respiration.
• The products of photosynthesis are the reactants of respiration.
• The products of photosynthesis are the products of respiration.

In photosynthesis, how is chemical energy stored?

• ATP
• Glucose
• Oxygen
• Carbon Dioxide

In respiration, how is chemical energy stored?

• ATP
• Glucose
• Oxygen
• Carbon Dioxide

What do animals do with the carbon dioxide produced in their cells during cellular respiration?

• store it for later use
• reuse it during photosynthesis
• exhale it in the breathing process
• combine it with water to make sugar

The following diagram shows the relationship between photosynthesis and respiration.  What products of photosynthesis are starting material for cellular respiration?

• glucose and oxygen
• heat energy and ATP
• carbon dioxide and water
• light energy and chlorophyll

Which conclusion best matches the trends shown on the graph?

• Bean plants produce more ATP than corn plants.
• Corn plants require more oxygen than bean plants.
• Corn plants release more carbon dioxide than bean plants.
• Corn plants produce sugars at a faster rate than bean plants.

How would light intensity generally affect the rate of photosynthesis?

• Increases the rate, up to a point
• Increases the rate
• Decreases the rate
• No relationship to the rate
