Diffusion is the process of molecules moving from high concentration to low concentration in a material. This will occur eventually through random movement and in simple diffusion is specifically without the aid of an intermediary such as integral membrane protein.
Simple diffusion means the movement of one substance from its' higher concentration to the lower. For example in a gas leak, the gas moves from its' point of origin (high concentration) away into the air (lower concentration). Another example would be adding sugar to tea. The sugar will move from the area where there is more sugar to where there is less sugar. In this case, equilibrium will be reached. It will take longer if it just sits for awhile.
Water moving in and out of a cell. This takes no energy and it moves from high to low.
from an area of higher concentration to an area of lower concentration.
Have fun with study island:)
The particles of a substance move from where they are in higher concentration to where they are in lower concentration.
The simplest form of diffusion is osmosis...with concentrations of the interior and exterior of a cell membrane reaching equillibrium.
no
Simple diffusion really says it for itself. Mostly simple molecules and substances can pass through. Water, O2 or CO2, or other small simple molecules are the limited spectrum of simple diffusion.
Passive transport is dependent on the permeability of the cell membrane, which, in turn, is dependent on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis.Simple diffusion is the unassisted passage of small, hydrophobic, nonpolar molecules.
Diffusion, specifically simple diffusion
Simple diffusion
simple diffusion.
no
simple diffusion, osmosis and facilitated diffusion.
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.

In simple diffusion, a substance passes through a membrane without any outside intermediary. The rate of diffusion is based on the force exerted..
Osmosis is one of the easiest-to-understand examples of diffusion. Past that, you will need to define 'simple'.
It doesn't. (answer by RRU member Cyrem)
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.

In Biology there are three types of diffusion. There are simple, channel, and facilitated diffusion.
