Matter and Energy in Living Systems
Plants use sugar molecules to make a variety of larger carbon-containing molecules that become part of their bod…
Item SB022001: Matter is not created when living organisms grow. The matter added to their bodies comes from atoms that were outside the organism.
Is matter created when living organisms grow?
- Yes, when living organisms grow, matter is created because new atoms are created.
- Yes, when living organisms grow, matter is created through cell division, and no additional atoms are needed.
- No, when living organisms grow, the matter that is added to their bodies comes from atoms that were outside the organism.
- No, when living organisms grow, atoms from the environment are turned into new types of atoms for the growing organism.

- 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.
