Cell Transport

Movement of molecules across the plasma membrane WITHOUT using cellular energy

• passive transport

• active transport

• endocytosis

• exocytosis

Goes WITH the concentration gradient (high to low concentration)

• passive transport

• active transport

• endocytosis

• exocytosis

movement  of particles from HIGH concentration to a LOW concentration

• osmosis

• diffusion

• facilitated diffusion

• phagocytosis

Diffusion of water through a selectively permeable membrane

• phagocytosis

• pinocytosis

• diffusion

• osmosis

Molecules diffuse across the plasma membrane with assistance from the membrane protein, such as channel proteins, gated ion channels and carrier proteins

• diffusion

• osmosis

• facilitated diffusion

• endocytosis

Concentrations of solute on both sides of membrane will be equal;

Water will move but there will be no net gain of movement

• isotonic solution

• hypotonic solution

• hypertonic solution

• bilateral solution

Concentrations of solute will be greater OUTSIDE the cell than inside so water will move OUT; Water is the equalizer to bring solute to homeostasis

• isotonic solution

• hypotonic solution

• hypertonic solution

• bilateral solution

Concentrations of solute will be greater INSIDE the cell than outside so water will move IN; Water is the equalizer to bring solute to homeostasis

• isotonic solution

• hypotonic solution

• hypertonic solution

• bilateral solution

Movement of molecules across the plasma membrane WITH using cellular energy

Goes AGAINST the concentration gradient (low to high concentration)

• passive transport

• active transport

• facilitated diffusion

• osmosis

Process of taking material INTO the cell by means of infolding (pockets) of plasma membrane

• exocytosis

• phagocytosis

• endocytosis

• pinocytosis
