It is called passive diffusion.
Movement across a membrane that does require energy is called active transport.
The movement of water across a membrane is called osmosis.
Diffusion is the simplest movement.
This type of movement is called simple diffusion.
The cell use something called a protein channel that helps larger particles across the cell membrane.
Movement across a membrane that does require energy is called active transport.
It is called passive diffusion.
it is called osmosis and it is the net movement of water particles across a semi-permable membrane against the concentration gradient!
The movement of water across a membrane is called osmosis.
... is called "facilitated diffusion".
Facilitated Diffusionosmosis & diffusion
Movement of water across a membrane is called OSMOSIS.
Diffusion is the simplest movement.
This type of movement is called simple diffusion.
The cell use something called a protein channel that helps larger particles across the cell membrane.
Osmosis is the movement of water across the membrane, while diffusion is the movement of solids across a membrane Diffusion ordinarily does not require a membrane.The movement of particles of a substance by their own kinetic energy from their higher concentration to lower concentration is called diffusion.
This type of movement is called simple diffusion.
