Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration so its overall net movement is along the concentration gradient. Simple diffusion does not require energy therefore it is 'passive', substances are diffused across the membrane between the phospholipids.
facilitated diffusion
Simple squamous epithelium has the shortest diffusion distance due to its thin structure, allowing for rapid diffusion of substances across the epithelium.
Facilitated diffusion needs some sort of help. Often it would be a protein. Simple diffusion doesn't. If you spill something smelly on the floor in the kitchen, you will smell it all through the house. It will spread by simple diffusion.
Osmosis is very similar to normal diffusion, but osmosis is only the movement of water through a "partially permeable membrane" where as simple diffusion is the movement of anything from an area of high concetrations to low, such as gas in a room.
This process is known as diffusion.
simple diffusion.
no
simple diffusion, osmosis and facilitated diffusion.
Simple diffusion.
In simple diffusion, a substance passes through a membrane without any outside intermediary. The rate of diffusion is based on the force exerted..
It doesn't. (answer by RRU member Cyrem)

both need transport protein
In Biology there are three types of diffusion. There are simple, channel, and facilitated diffusion.
