How is osmosis a special kind of diffusion?
Osmosis is the diffusion of water only. Osmosis occurs when water moves across a membrane in order to create an equilibrium.
How does water move in osmosis?
Osmosis moves a solvent (eg water) to balance the concentrations of solute either side of a semipermeable membrane. The solvent is not lost.If the concentration of a solution is higher on one side of the membrane than the other, then the water moves across the membrane from the less concentrated side to the more concentrated side to dilute it until the concentrations on either side are equal.
How does osmosis form?
Osmosis is a physical process in which a solvent moves, without input of energy, across a semipermeable membrane (permeable to the solvent , but not the solute) separating two solutions of different concentrations. Osmosis releases energy, and can be made to do work, as when a growing tree root splits a stone.
How is active transport different then osmosis?
Osmosis is the diffraction of water through a permeable membrane using no energy, whereas active transport is the moving of particles across a membrane against a concentration gradient. Basically, Osmosis moves water with no energy. Active transport moves particles, in general, with the use of chemical energy like ATP.
Explain how osmosis differs from diffusion?
Osmosis differs from Diffusion because in osmosis only water moves, and during diffusion, small molecules move across the cell membrane.
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
The process of moving materials across the cell membrane without the expenditure of energy is called passive transfer
Name the process by which oxygen moves across the wall of the alveolus?
diffusion
What is the process which water moves across the cells membrane?
The water moves from an area of high concentration to an area of low concentration across the semi permiable membrane using osmosis.
What moves particles like oxygen into cells?
Oxygen diffuses directly across the cell membrane and requires nothing to carry it.
Which process moves an ion across a cell membrane against a concentration gradient?
ative transport
What process do water molecules cross the cell membrane?
Process in which water molecules moves across a membrane?
What substance undergoes osmosis?
Water moves across the cell membrane through the process of osmosis.
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.
The energy-requiring process that moves molecules and ions across a cell membrane against a concentration difference is called?
Active transportation

transportation
