Diffusion and osmosis differ because diffusion is the process by which molecules spread out, or move from areas with high concentration to low concentration, and osmosis is the diffusion of water.
Osmosis is a type of diffusion relating to water. It is usually used to describe the diffusion of water across a membrane (such as the cell membrane).
Osmosis is also defined as the flow of solvent from a region of higher pressure toward a region of low pressure.
The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. Osmosis always deals with the movement of water across a semipermeable membrane. Water always moves toward the side that is higher in solutes (mainly salt). It does this to balance the two sides. Osmosis always follows salt is one of the best ways to remember this.
a metal would deposit on another in two ways diffusion or electrolysis
http://www.answers.com/topic/osmosis The applications listed on that website are very informative, but the description of osmosis is lacking a few details. It would be a good idea to supplement your reading of that web page with this information:It is a common misconception that osmosis is the diffusion of water in only one direction. In reality, water molecules will diffuse in both directions during osmosis, but the rate of diffusion from a region of high water potential (low solute concentration) to a region of low water potential (high solute concentration) will be higher than the rate of diffusion back into the region of high water potential/low solute concentration. Thus osmosis is the net movement of water across a semi-permeable membrane, from a region of high (more positive) water potential to a region of low (more negative) water potential. The word 'net' is very important in this definition, as it illustrates that we are referring to the overall effect, rather than individual molecular movements.It is also important to remember that osmosis does not stop when "there is an equal solute concentration on both sides of the membrane". Osmosis will 'stop' when the water potential on either side of the membrane is equal, which may occur when one side still has a higher solute concentration, since other factors also effect osmosis (eg pressure). Even when osmosis 'stops', water will still diffuse in both directions, but at equal rates (the system has reached equilibrium).
Science disciplines differ from one another in terms of exactness. While some sciences can be absolute, such as chemistry, the science of psychology is nowhere near to being an exact science.
Osmosis certainly does happen regularly in real life. Osmosis is the transportation of water from one side of a membrane to the other side of a membrane.
diffusion. Osmosis is movement across a semipermeable membrane
yes
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the movement of water molecules from high to low through a partially-permeable membrane. This is what makes osmosis different to diffusion.
Osmosis and diffusion are the same because they are both ways that molecules are carried across the cellular membrane with the concentration gradient.
One method of movement across the membrane is by diffusion, which is related to osmosis.
Yes, diffusion is an example of how particles move from an area of higher concentration to an area of lower concentration, which can explain how the smell of burnt toast can spread from one room to another.
The differences between diffusion and osmosis are really just that osmosis takes place with water and through a membrane. Diffusion is just the spread of molecules from high concentration to low. Osmosis is diffusion of water through a membrane.
The term for the diffusion of water across a semipermeable membrane is osmosis. Osmosis is when the molecules of a solvent move from a less concentrated solution to a more concentrated one. This equalizes the concentrations on each side of the member.
Diffusion is when there is lower concentration in one area than another so the particles that are in the area with higher concentration move to the area with lower concentration to make the concentration same in both areas. Osmosis is a type of diffusion but diffusion that only has water involved. So if there's no water... it's not osmosis. It's gotta be diffusion.
Diffusion is the movement of particles from an area of high concentration to an area of low concentration, which helps cells take in nutrients and get rid of waste. Osmosis is the diffusion of water across a selectively permeable membrane, allowing cells to maintain their internal balance of water and solutes. Together, diffusion and osmosis are essential processes for cells to function properly and maintain homeostasis.
There's facilitated diffusion, where proteins channel in molcules; then there's active transport where the cell uses energy to bring in molecules that are to large or a different chemical configuration.
One similarity between osmosis and facilitated diffusion is that both involve the movement of molecules across a membrane from an area of high concentration to an area of low concentration, driven by a concentration gradient.
