ability to maintain constant internal balance regardless of the environment (steady state)
-occurs at all levels
-cells exist in fluid environment
-cells must keep cytoplasm
4 factors decide what go through (homeostasis)
-dissolves in water
-conditions inside & outside the cell
At cellular level, homeostasis depends on movement....
in & out of the cell
-all things must pass through cell membrane
moving particles from high to low concentration
-possible because of kinetic energy (energy of motion) atoms move in a straight line
-atoms keep moving til their spread evenly
moves molecules and particles into the cell
-phagocytosis - cytoplasm surrounds the particles
-pinocytosis-collects on the cell membrane and pinches inward
