Diffusion - Mrs. Bader

Cellular Transport By: Alexandra Definition Of Diffusion Diffusion is the movement of particles from a higher concentration

to a lower concentration. The process of diffusion continues until the particles are evenly distributed. Examples Of Diffusion Some examples of objects that use

diffusion is the smell of perfume when it spreads through a room, the smell of fresh baked cookies throughout the house and when a helium balloon slowly deflates to distribute the helium.

Definition Of Osmosis Osmosis is a kind of diffusion that involves only the movement of water through a selectively permeable membrane. Osmosis helps the cell

because it allows substances the cell needs to go in and keeps the bad substances out. Examples Of Osmosis Some examples of osmosis are

strainers, water purifiers, tea bags, coffee filters and food. Other Definitions Cellular Transport- movement of substances in

and out of the cell. Permeable- particles can pass through easily. Impermeable- particles can not pass through. Selectively Permeable- only allows

some substances through. OSMOSIS DIFFUSION

A Poem About Diffusion by:Alexandra From a high concentration to a low concentration, The particles give their demonstration.

First theres a smell over here, Suddenly its over here. Even amounts everywhere. Even amounts

every where. Even amounts everywhere. Even amounts everywhere. Even amounts everywhere even amounts everywhere. Even amounts everywhere. Even amounts everywhere. Even amounts everywhere. Even amounts everywhere. Even amounts

everywhere. Even amounts every where. Even amounts everywhere. Even amounts everywhere. Even amounts everywhere. It mixes... Here and there

there and here there

here there and here

here and there here there

and and Magically it moves

From here across the room Now everyone can smell Diffusion from Taco Bell.
