Key Concept What is cellular respiration?
Directions: On the line before each statement, write T if the statement is true or F if the statement is false. If the
statement is false, change the underlined word(s) to make it true. Write your changes on the lines provided.
1. Energy is required by all organisms for life.
2. Cellular respiration converts energy from the Sun into food molecules,
3. Glucose molecules are broken down into carbon and oxygen.
4. The process of cellular respiration is necessary for a plant to grow and
reproduce.
5. Cellular respiration takes place in chloroplasts.
6. Cellular respiration requires water and produces carbon dioxide as a waste
product.
7. Cells must be able to break down glucose because the energy stored in it is too
powerful for cells to use it all at once.
8. The chemical bonds in food molecules provide energy for life.

9. The ability of a plant to repair tissue depends on cellular respiration.
10. Cellular respiration involves a series of chemical reactions.
11. ATP molecules result from the breakdown of water and oxygen.
12. Cellular respiration can occur without photosynthesis.
