Passive And Active Transport Flashcards
Passive transport. Water molecules. High to low concentration.
Osmosis
Passive transport. High concentration to low. Small particles
Diffusion
Passive transport. Large particles. Travel through channels and carriers. High to low concentration
Facilitated diffusion
Active transport. Moves large particles IN to the cell.
Endocytosis
Active transport moves large particles OUT of the cell.
Exocytosis
Maintains a constant internal environment despite changes in external environment.
Homeostasis
Passive transport examples?
Osmosis , diffusion , facilitated diffusion.
Active transport examples ?
Endocytosis. Exocytosis
When the concentration is the same on both sides of the membrane
Equilibrium
A solution that causes a cell to shrink. When concentration is higher outside.
Hypertonic
A solution that causes a cell to swell. When concentration is lower outside
Hypotonic
A solution that causes no change. Concentrations the same inside and outside
Isotonic
Movement of particles that needs assistance
Facilitated diffusion
Cell engulfs particles using the cell membrane to make vesicles.
Endocytosis
Used by cell to release large amounts of material
Exocytosis
