or
smelling cookies baking when you are in your room
are examples of.....
diffusion
400
Why does the cell do osmosis and diffusion?
Two get need materials like food, water and oxygen.
400
During active transport molecules move from a _________ to a _________ .
low concentration to a high concentration
400
In which organelle is food energy converted to energy that the cell can use
mitochondria
400
What organelle is a storage area for the cell

500
some molecules are able to move into the cell membrane and some are not. What is the term for this?
Selectively permeable
500
This form of cell transport is so important to the cell it gets its own name, even though it is very similar to diffusion.
Osmosis
500
When does active transport happen?
When the cell needs to take in a substance that is in a higher concentration inside the cell than outside the cell.
500

______________contains chemicals that break down certain materials in the cell
