Study Notes

Life Processes

  • Life processes are a set of activities that occur within living organisms to maintain life.
  • A key characteristic of life processes is that they are continuous, meaning they happen constantly throughout an organism's existence.
  • Examples of life processes include growth, reproduction, respiration, nutrition, and excretion.
  • Life processes are defined as the essential functions that allow living organisms to survive, grow, and reproduce.
  • Sleeping is not an example of a life process, as it is a state of rest rather than an essential function for survival.
  • The purpose of life processes is to maintain homeostasis or a stable internal environment within an organism.
