Dissolved particles on one side of the membrane results in the diffusion of water across the membrane due to the need to have the same solution concentration on both sides of the membrane. Water will diffuse from a hypotonic solution to a hypertonic solution.
Yes. It is called Osmosis. Particles move across the membrane in order to balance the concentration of particles on both sides of the membrane. Since the membrane tends to block the larger particles, its the smaller molecules that move, so what happens across membranes is that the motion (of say water) is from low concentration toward higher - but the result is to even the concentration on both sides of the membrane, Pure diffusion is always from higher concentration to lower.
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
Facilitated diffusion does not require energy for the transportation of molecules across the cell membrane.
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
facilitated diffusion
Movement across a membrane that does require energy is called active transport.
When one area has a higher concentration than another area substances move from the area of high concentration to the area of low concentration.
Diffusion and Osmosis
Equilibrium in diffusion and osmosis is reached when there is a balanced distribution of particles or solutes across a membrane, resulting in no net movement of particles. In diffusion, equilibrium is reached when there is an equal concentration of particles on both sides of the membrane. In osmosis, equilibrium is reached when the water concentration is the same on both sides of the membrane.
... is called "facilitated diffusion".
It is called passive diffusion.
It is called passive diffusion.
Facilitated Diffusionosmosis & diffusion
Things move across the membrane from lower to higher concentrations by active transport.
Solvent particles will move from an area of high concentration to low concentration across a semipermeable membrane until equilibrium is reached. This process is known as osmosis and is driven by the natural tendency of molecules to move from areas of high to low concentration to equalize the concentration gradient.
equalize the concentration on both sides of the membrane through passive diffusion.
