What Word Goes in There As cell size goes effectiveness of diffusion and osmosis goes This drives the cells to stay small?
as a cell goes blank effectiveness of diffusion and osmosis goes bank.
Passive and active transport?
Active Transpot. -Pumps -Endocytosis -Exocytosis Passive Transport - Diffusion -osmosis -Facilitated Diffusion active requires energy passive doesnt. active against concentration gradient, passive along concentration gradient.
Is facilitated diffusion type of active transport?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
What is the movement of molecules from areas of higher concentration to lower concentration until equilibrium is met?
The movement of particles from an area of high concentration through a semi-permeable membrane to an area of low concentraton is the process of diffusion. I'm sorry but I do not think that answer is good enough. It is a form of diffusion, where only small particles, small enough to pass through the membrane can get through. When I was in school the statement above was the definition of osmosis, the whole point being it was diffusion through a semi-permeable membrane, selecting for only small enough particles. It seems some time between 1992 and 2003 the definition was changed to the movement of water, and not particles and now in 2010 the definition is the movement of solvents. I would like to know how and why the definition osmosis was changed, why and what is the justification? I would also like to know why the original meaning of osmosis, which made perfect sense, has been changed to "it's the definition of diffusion and not osmosis any more", when in fact it isn't a clear enough word to describe the process? Surely the new definition of osmosis is also diffusion?
What is the difference between facilitated diffusion with help of the carrier molecule and active transport with help of a transport protein?
The most essential difference is that one is active (uses energy) and one is passive (doesn't require energy). Take note whenever you see the word 'active' in this context- it denotes that energy is required for it to occur, usually against the concentration gradient. Facilitated diffusion is just another passive process by which molecules move from an area of high concentration to low concentration. Note that this requires no energy to occur, except it differs from diffusion in that a carrier molecule is required (usually because the molecule is too large to freely cross the plasma membrane)
Osmosis and raw egg and salt?
Osmosis only apply to water, the word your looking for is Diffusion

Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
What are metaphors for 'diffusion'?
Diffusion is the movement of a mineral or nutrient moving across the concentration gradient of a membrane. The closest word to diffusion would probobly be osmosis, which is the movement of water through a membrane.
What is another term for the diffusion of water?
I think the word you're looking for is osmosis. Water with different ionic or molecular concentrations will move toward equilibrium.
Is facilitated diffusion type of active transport?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
What stems are in the word osmosis?
The English word osmosis stems from the Greek word osmos,meaning "impulse".
How do you sue osmosis in a sentence?
the word osmosis is hard to say.
A sentence with the word osmosis?
Today we learned about osmosis in school
