What impact does osmosis and diffusion have on life?
If osmosis and diffusion didn't exist then cells In things would be dry and shrink
How does osmosis and diffusion work in amoeba?
Amoeba obtains oxygen via diffusion; it takes in water by osmosis, but I would think this is more of a problem, since Amoeba lives in a freshwater environment, and water is always entering by osmosis. Amoeba's problem is getting rid of that water, which it does by means of contractile vacuoles.
What 3 ways can substances enter and leave a cell?
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
What is the process in which molecules move in and out of cell?
The movement of things through the cell would be called diffusion. If it is water we are talking about then it is called osmosis. diffusion and osmosis are examples of inactive transport. Active transport involves specific proteins in the cell that pull material in the cell though the cell membrane.
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?
How does water enter or leave the uni cellular organism by diffusion or osmosis?
osmosis is a form of diffusion. in regard to water, the diffusion type would be osmosis
What would osmosis be in a house?
Diffusion?
What impact does osmosis and diffusion have on life?
If osmosis and diffusion didn't exist then cells In things would be dry and shrink
What does reverse osmosis do?
When a plant is wilting (which is due to plasmolysis of plant cells caused by diffusion), water it and it would become a hypotonic solution. Water enter plant cells and this increases turgor pressure, enabling plants to be upright.
What cellular process does not require ATP?
Diffusion and Osmosis.... I think. It would be better to double check ;)
Are diffusion and osmosis types active transport?
No. (Active xport would be in the opposite direction.)
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.
Is it osmosis or diffusion if you put an egg in vinegar?
If you put an egg in vinegar, then this process would be called osmosis because osmosis is the movement of solvent particles (in this vinegar), while diffusion is the movement of gas, solute and solvent particles from a region of higher concentration to a region of lower concentration.

Why are the processes of osmosis and diffusion essential for life?
Because without them, your nipples would not produce mountain dew.
What is the only substance that can carry out osmosis?
Strictly speaking, osmosis means the diffusion of waterthrough a semipermeable membrane. I'm not certain what the generic term for other solvents would be.
How would you use osmosis in a sentence?
Osmosis is the diffusion of water molecules from an area of high concentration to an area of low concentration, usually through a semi-permeable membrane.
