Study Notes
Cellular Functions
- Cells are the smallest unit of an organism.
- Cells perform various functions in an organism, including nutrition and reproduction.
- Cells need energy to perform their functions.
Respiration
- Breathing, or respiration, is necessary to provide oxygen to cells.
- We breathe to obtain oxygen, which is necessary for cellular functions.
- Boojho breathed rapidly after running because his body needed more oxygen to recover from the physical activity.
Cell Energy
- Breathing is not a part of excretion, but rather a process that provides energy to cells.
- Cellular functions, such as nutrition and reproduction, require energy obtained through breathing.
