How do things get in and out of cells?
Jeremiah AllenMostly through Osmosis or Diffusion. Examples: Water, Carbon dioxide, Oxygen etc
Here is a video which describes how osmosis impacts onion cells placed into tap water and then into a salt water solution. Changes in the cells are caused by the movement of water into or out of the cells.
Hope this helps!

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
