- in, this is called osmosis. it is a form of passive transport driven by the higher solute concentration inside the cell than outside. it requires no energy to run.
- out, this is called reverse osmosis. it is a form of active transport driven by higher pressure inside the cell than outside. it requires energy to create and maintain the pressure difference. living cells do not use this, instead they use a form of active transport involving pore pumpsembedded in the membrane to remove excess water and other undesired chemicals from the cell.

'What is it called when water diffuses into a plant cell and builds up firm pressure?
tugor pressure
What is an example of molecules that diffuses out of a cell?
Water, sodium, potassium, glucose all diffuse in and out of the cell.
What happens to a cell in a hypertonic solution?
water moves out. when water diffuses out of the cell, the cell shrinks, that is Hypertonic solution.
Osmosis can be defined as?
Osmosis is a type of passive transport that occurs when water diffuses through a cell membrane.
What is the process in which water diffuses through a cell?
That would be osmosis, which is when items go from a low concentration to a high concentration.
The water in a cell does what?

How do unicellular get water?
Water diffuses across their cell membranes
Why does a cell diffuse items into the cell?
The cell needs food and water so it diffuses it to maintain health.

What would happen if a cell placed in a hypotonic solution?
When a cell is placed in a Hypotonic solution, the water diffuses into the cell, causing the cell to swell and possibly explode.
