Let's analyze each description in relation to photosynthesis and cellular respiration:
-
Involves at least one chemical reaction
- Both photosynthesis and cellular respiration (Both processes involve multiple chemical reactions.)
-
Rearranges carbon, hydrogen, and oxygen atoms
- Both photosynthesis and cellular respiration (Both processes involve the rearrangement of these atoms; photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration breaks down glucose into carbon dioxide and water.)
-
Occurs in cells in green plants
- Photosynthesis only (Photosynthesis primarily occurs in the chloroplasts of green plant cells.)
-
Occurs in cells in animals
- Cellular respiration only (Cellular respiration occurs in all living organisms, including animals, whereas photosynthesis occurs predominantly in plants.)
-
Produces glucose that can be stored for later use
- Photosynthesis only (Photosynthesis produces glucose, which can be stored as starch in plants; cellular respiration breaks down glucose for energy.)
-
Uses glucose as a source of energy
- Cellular respiration only (Cellular respiration uses glucose to produce ATP, the energy currency of the cell, while photosynthesis generates glucose from light energy.)
Summary:
- Both: Involves at least one chemical reaction, Rearranges carbon, hydrogen, and oxygen atoms
- Photosynthesis only: Occurs in cells in green plants, Produces glucose that can be stored for later use
- Cellular respiration only: Occurs in cells in animals, Uses glucose as a source of energy
