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.

From a high concentration to a low
concentration,The particles give their demonstration.

First there’s a smell over here,
![Page 13: Cellular Transport](https://reader030.vdocuments.us/reader030/viewer/2022033106/568166f0550346895ddb4d35/html5/thumbnails/13.jpg)
Suddenly it’s 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 andhere there here here and
there and there
here here and there and

Magically it moves
From here across the room

Now everyone can smell
