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?
Diffusion occurs from an area of high concentration to an area of low concentration. The rate of diffusion is influenced by factors such as temperature, concentration gradient, and the size of particles. Diffusion is a passive process that does not require energy input from the cell.
Is diffusion a form of active transport?
No, diffusion is not a form of active transport. Diffusion is a passive process where molecules or ions move from an area of high concentration to an area of low concentration, driven by the concentration gradient. Active transport, on the other hand, requires energy expenditure to move molecules or ions against their concentration gradient.
Is diffusion passive or active transport?
Diffusion is passive, it happens everywhere whether living things are involved or not. It results from the natural thermal motion of particles.
In facilitated diffusion which process does not require energy?
Simple and facilitated diffusion are a part of passive transport. This refers to the movement of molecules, atoms and ions across the cell membrane. In both of these processes, molecules move from areas of high concentration to areas of lower concentration because equilibrium is trying to be maintained in living organisms. Simple diffusion just happens randomly and without any aides. Facilitated diffusion uses proteins in the cell membrane to guide polar molecules and ions in and out of the membrane (always to areas of lower concentration) and DOES NOT require ENERGY.Only active diffusion requires energy.
What special form of diffusion tgat applies only to water?
Osmosis is a special form of diffusion that applies only to water molecules. It involves the movement of water from an area of low solute concentration to an area of high solute concentration through a semi-permeable membrane.
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.
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.
Is osmosis a form of diffusion?
Yes, osmosis is a specific type of diffusion in which water molecules move across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
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.
Movement of water down its concentration gradient?
Osmosis is the movement of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. This process is passive and does not require energy input. Osmosis plays a crucial role in maintaining the balance of water in cells and tissues.
What form of diffusion cannot be transmitted by media?

Does sodium move by active transport?
Sodium ions are thought to get into a cell by diffusion through special spores in the membrane and are expelled by a form of active transport .
