simple and fascillitated
simple--> doesn't need help from protein channels on cell membranes
Diffusion-the random movement of molecules from an area of higher concentration to an area of lower concentration.Osmosis-the diffusion of water across a semipermeable membrane.
1. facilitative diffusion-transport proteins provide a pathway for certain molecules to pass 2. osmosis-the passive transport of water across a selectively permeable membrane 3. diffusion- the net movement of the particles of a substance from where they are more concentrated to where they are less concentrated. (out of a sophomore Biology book)... hope this helps <3
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. It can occur in various places, but commonly happens in cells and in the lungs. In cells, diffusion helps with the exchange of nutrients and waste products. In the lungs, oxygen moves from the air sacs into the bloodstream, while carbon dioxide moves out of the blood and into the air sacs for exhalation.
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
Passive transport is when molecules pass freely through the membrane moving from the higher concentration area to the region of lower concentration. Three examples of this are diffusion, osmosis, and active transport.
what id diffusion? what are the three types?Diffusion is the second important concept for understanding how culture change. type 1) expansion, type 2) relocation type 3) hierarchical
PASSIVE TRANSPORTS ARE OF TWO TYPES. 1)SIMPLE DIFFUSION 2)FACILITATED DIFFUSION 1)SIMPLE DIFFUSION:-diffusion of water and dissolved gas is simple. when concentration on both sides of membrane becomes the same,it stops. 2)FACILITATED DIFFUSION:-this also occurs along concentration gradient with help of carrier molecules.

simple diffusion, facilitated diffusion, and osmosis (water)
Diffusion - spreading of molecules in solid, liquid and gas Osmosis - diffusion of water; affected by tonicity Facilitated diffusion - transports of substances are facilitated by carrier proteins
