The+Cell+in+Action

Summary
====The section "Exchange With the Environment" is about finding correlation between a cell and its environment. Most of it takes place in the cell membrane. A helpful source to know how materials move into and out of a cell is diffusion. You will need this to obtain energy and to also get rid of wastes. The way you transport is with passive and active transport. You will also learn about osmosis. ====

Notes/Important Ideas

 * Cells don't need to use energy for diffusion to occur
 * All organisms need water to live.
 * Cells use energy when Active transport occurs. The energy comes from the ATP
