Ecosystems review with focus on cellular respiration

Multiple Choice

Which one do plants perform?

• Photosynthesis

• Cellular respiration

• Both of the other options are correct

Plants store energy from the Sun using photosynthesis, but then they release the energy to use it in their cells through cellular respiration.

Multiple Choice

What is the purpose of photosynthesis?

• to store energy as food molecules

• to release energy

Multiple Choice

Which of these is a food molecule that stores energy (thanks to photosynthesis)?

• carbohydrates

• ATP

• both of the other options are correct

Plants store energy in food molecules such as carbohydrates.

ATP, on the other hand, is a molecule that acts as a sort of energy shuttle for quick delivery of energy, not storage.

Multiple Choice

Which of these is an energy shuttle that delivers energy in cells (as opposed to storing it)?

• carbohydrates

• ATP

Multiple Choice

What is the purpose of cellular respiration?

• to store energy as food molecules

• to release energy

Multiple Choice

Based on the BrainPOP, cellular respiration releases energy as...

• ATP

• proteins

• carbohydrates

• fats

Multiple Choice

Photosynthesis produces...

• carbon dioxide

• oxygen

Multiple Choice

Cellular respiration produces...

• carbon dioxide

• oxygen

Multiple Choice

In which way are photosynthesis and cellular respiration different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.
• Cellular respiration produces oxygen, while photosynthesis uses oxygen.
• Photosynthesis releases energy, while cellular respiration stores energy.
• Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.

The first answer was incorrect because cellular respiration releases ATP, while photosynthesis stores energy in food molecules (not the other way around).

The 2nd answer is incorrect because cellular respiration produces carbon dioxide, not oxygen.

The 3rd answer also reverses the correct answers.
