Osmosis refers to water going across a membrane. It is the same as the diffusion of any other chemical, but this term designates only the diffusion of water.

Is diffusion through ion channels a form of active transport?
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
What are the three rules that apply to diffusion?
Form high to low concentration molecules balenced water goes where their is more concentration
Is diffusion a form of active transport?
NO
How does osmosis explain the fact that watery syrup forms when you put sugar on strawberries?
Osmosis is the diffusion of water across a membrane from the side of higher concentration to lower concentration. When sugar is placed on strawberries, the water diffuses across the cell membranes out of the strawberries and mixes with the sugar to form a syrupy substance.
Facilitated transport means?
Facilitated diffusion Facilitated diffusion in cell membrane, showing ion channels and carrier proteins Facilitated diffusion (or facilitated transport) is a process of diffusion, a form of passive transport facilitated by transport proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism. Polar molecules and charged ions are dissolved in water but they can not diffuse freely across cell membranes due to the hydrophobic nature of the lipids that make up the lipid bilayers. Only small nonpolar molecules, such as oxygen can diffuse easily across the membrane. All polar molecules should be transported across membranes by proteins that form transmembrane channels. These channels are gated so they can open and close, thus regulating the flow of ions or small polar molecules. Larger molecules are transported by transmembrane carrier proteins, such as permeases that change their conformation as the molecules are carried through, for example glucose or amino acids. Non-polar molecules, such as retinol or fatty acids are poorly soluble in water. They are transported through aqueous compartments of cells or through extracellular space by water-soluble carriers as retinol binding protein. The metabolites are not changed because no energy is required for facilitated diffusion. Only permease changes its shape in order to transport the metabolites. The form of transport through cell membrane which modifies its metabolites is the group translocation transportation.
What special form of diffusion tgat applies only to water?
Osmosis is the form the applies only to water. This is only in high waters.
Osmosis is a special form of?
Osmosis is a special form of diffusion in that it brings water into a cell, rather than nutrients & other substances.
Is osmosis a form of diffusion?
Yes. Osmosis is a special case of diffusion - in involves just water diffusing across a semipermeable membranes - like in cell membranes.
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
Movement of water down its concentration gradient?
Diffusion is the movement of water from a higher concentration of water to a lower. Osmosis is a special form which requires a cell membrane.
When you breathe on mirror water droplets form this is an example of?
diffusion
What term refers to the movement of molecules from a higher concentration to an area of lower concentration?
Diffusion, a form of passive transport, is the movement of molecules from an area of greater concentration to an area of lower concentration. Osmosis is a special case involvement the movement of water from an area of higher concentration of water molecules to an area of lower concentration of water molecules. It takes place in all three states of matter-Solids, liquids and gases.
Absorbtion of water by plant is an example of?
Absorption of water by plants is a form of diffusion called osmosis.
Why is osmosis special type of diffusion?
Osmosis is considered a specialised type of diffusion because it ONLY involves water passing from a region of high water potential to an area of low water potential through a partially-permeable membrane. Osmosis takes place primarily in our small intestines, where water is absorbed.
What are molecules that tend to move form an area of high concentration?
Diffusion is the general term. Osmosis is the diffusion of water through a semi-permeable membrane.
What form of diffusion cannot be transmitted by media?
relocation diffusion
Is a specialized form of diffusion and diffusion is a type of passive transport.?
membrane
