Diffusion is a process that occurs naturally everywhere. All molecules and particles that are in an area of higher concentration in a gas or liquid will tend to move to an area of lower concentration. That is diffusion.

∙ 14y agoDiffusion is one type of transport phenomenon. Diffusion is the movement of particles from higher chemical potential to lower chemical potential (chemical potential can in most cases of diffusion be represented by a change in concentration). It is readily observed, for example, when dried food like spaghetti is cooked; water molecules diffuse into the spaghetti strings, making them thicker and more flexible. It is a physical process rather than a chemical reaction, which requires no net energy expenditure. In cell Biology, diffusion is often described as a form of passive transport, by which substances cross membranes. Diffusion is, in essence, molecules moving around until they're evenly spead out in an area.
Hope this helps :D

∙ 14y agoDiffusion is when particles move from an area of higher concentration to an area of lower concentration and occurs only when the cell membrane is (semi-)permeable to that particle. A proper analogy would be stuffing hundreds of people in a crowded room and then opening the door into an empty, adjacent room. People would cross into the empty room where there is more space to spread out. This is what diffusion is like.

What part of an animal cell allows diffusion and osmsis occur?
the cell membrane
When does diffusion occur across a cell membrane?
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
Where in the membrane does facilitated diffusion occur?
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
What cellular process causes the movement of the oxygen into the cells from the blood?
Pizza
If diffusion is going to occur there has to be what?
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
Where diffusion occur?
Diffusion occurs on the cell membrane.
What part of an animal cell allows diffusion and osmsis occur?
the cell membrane
When does diffusion occur across a cell membrane?
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
What process causes water to or leave cell?
diffusion
Does diffusion require the cell to respire?
Diffusion is a form of passive transport, so nothing is required for it to occur.
What doesn't occur as a cell grows larger in size?
Diffusion across the cell membrane is impaired
What are the consequences for a cell if it cannot carryout osmosis and diffusion effectively?
The cell will work but not very well because osmosis and diffusion did not occur but sometimes it will work anyways
What process cause the water to enter or leave the cell?
the process that causes the water to enter and leave the cell is diffusion
How diffusion will occur?
diffusion is occur when different concentration gradient is applied
When reffering to molecular transport does movement occur across the cell membrane?
yes, it can occur in various ways. (active transport, simple diffusion,etc.)
Where in the membrane does facilitated diffusion occur?
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
What cellular process causes the movement of the oxygen into the cells from the blood?
