Item SB064001: Both plant growth and animal growth involve chemical reactions because both use chemical reactions to build larger molecules that become part of their bodies.
Are chemical reactions involved during plant or animal growth?
- Both plant growth and animal growth involve chemical reactions because both animals and plants use chemical reactions to build larger molecules that become part of their bodies.
- Only plant growth involves chemical reactions because plants use chemical reactions to make their food and animals do not.
- Only animal growth involves chemical reactions because animals use chemical reactions to digest their food but plants do not.
- Neither animal growth nor plant growth involves chemical reactions because chemical reactions do not occur in living things.

- Disciplinary Core Ideas
- LS1.C Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used immediately or stored for growth or later use.
LS1.C Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules, to support growth, or to release energy.
