The random movement of molecules and ions down their concentration gradient (meaning from an area of high concentration to an area of low concentration) is called simple diffusion. Simple diffusion is related to the magnitude of driving force, permeability of the membrane, and surface area.
Facilitated diffusion is the movement of a molecule down its concentration gradient with the assistance of a membrane protein. This is a type of passive transport (no energy is required).
Facilitated diffusion
The answer is Active Transports
diffusion. for water, its osmosis
Passive transport
Passive Transport
Diffusion is the net movement of particles(atoms,ions or molecules) from a region where are of higher concentration to a region where they are of lower concentration, down a concentration gradient.Factors that affect the rate of diffusion1.Temperature2.the concentration gradient3.Physical movement4 surface area to volume ratioThe passage of water from the less concentrated solution to the more concentrated solution across a partially permeable membrane is a process called osmosis
Molecules tend to move into areas where there are less molecules. This is called diffusion and can happen with or without energy.
I assume you're talking about Osmosis, but I believe there are actually other similar processes as well.
DIFFUSIBILITY The quality of being diffusible; capability of being poured or spread out.
Air molecules do not attract odors. It is a natural process called diffusion, in which particles move from an area that has a high concentration of itself to a place where there is a lower concentration of itself.
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
water uptake at the roots is called osmosis,this is the movement of water molecules from a region of lower concentration to a region of higher concentration against concentration gradient
Its called as Osmosis
The movement of molecules from great concentration to lesser concentration is called diffusion. However when dealing water molecules it is referred to as osmosis.
Movement of molecules 4m higher to lower concentration is called osmosis
Molecules can move against concentration gradient by a movement called active transport. Molecules move from an area of low concentration to an area of high concentration by using chemical energy called ATP or an electrochemical gradient--either way, it uses cellular energy.
Concentration Gradient
Active transport: The movement of particles against the concentration gradient into or out of a cell. Bulk transport:The movement of large molecules into or out of the cell. Both of these require energy
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
This process is called diffusion. It is the passive movement of particles from high to low concentration, and is against a concentration gradient. Hope this helps!
it is called a concentration gradient.
