Cell transport is the process in which materials are moved into or out of a cell.
Two main types of cell transport are active and passive transport.
Cell transport
1. 1. occurs at the cell membrane.
  2. Is affected by concentration and environmental condition.
Size, shape, and charge all affect how materials enter or exit a cell.

This video provides an overview of all aspects of cell transport.

This video provides a summary of the three types of active transport with examples of times they are needed.

This is an annimation explanation of how cells respond to different tonicities

Active transport requires ATP; passive does not require ATP.
Active transport goes against or up a concentration gradient; passive goes with or down the concentration gradient.
Active transport includes
1. 1. endocytosis (phagocytosis and pino cytosis are examples of endocytosis)
  2. exocytosis
  3. the sodium-potassium pump
Passive transport includes diffusion, facilitated diffusion, and osmosis.
Water will travel across a cell membrane to where there is less water/more solute.
During passive transport, solute concentration affects movement of particles.
