Cells use two different types of transport to ensure homeostasis within the cell itself. The plasma membrane is a selectively permeable membrane that allows the cell to
regulate its internal environment. The two types of transport are passive and active. Passive transport is a process by which substances move across the membrane moving
from a high concentration gradient to low concentration gradient, whereas active transport requires the use of energy and substances must move against the concentration
gradient by moving from an area of low concentration to an area of high concentration.
Use the following graphic organizer to identify the mechanisms of transport that cells utilize.
Fill in the boxes with the following:
Passive Transport
High Low Concentration
Osmosis
Excocytosis
Pinocytosis
Cell Transport
Diffusion
Phagocytosis
Facilitated Transport – using carrier proteins
Active Transport
LowHigh Concentration
Hypertonic
Water flows OUT of the cell
Isotonic
Water moves in and out of the cell - Equilibrium
Hypotonic
Water flows INTO the cell
Protein Pump
Sodium/Potassium
Endocytosis
No Energy Needed
