Is it from high concentration to low that particles move across a membrane move?

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.

What is osmosis function?
This is the movement of water particles from an are of high concentration to an area of low concentration through a partially permeable membrane.
Is movement of water from an area of high concentration to an area of low concentration across a?
across semipermeable membrane? That is osmosis, the net movement of water.
What is the process which water moves across the cells membrane?
The water moves from an area of high concentration to an area of low concentration across the semi permiable membrane using osmosis.
What is process that moves molecules across a cell membrane from regions of lower concentration to higher concentration?
The process that can move molecules from a low to a high concentration through a cell membrane is active transport.
What is ozmosis?
ozmosis is the movement of water from an area high concentration of water to low concentration of water, across a semi-permiablw membrane
Is the process in which molecules move across a cell membrane from a region of low concentration to a region of high concentration.?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
Why do dissolved particles on one side of a membrane result in the diffusion of water across the membrane?
When one area has a higher concentration than another area substances move from the area of high concentration to the area of low concentration.
Define osmosis and diffusion?
Osmosis is the random movement of particles across (through) a partially permeable membrane along a concentration gradient from an area of high concentration to an area of low concentration. Diffusion is the random movement of particles in a solution from an area of high concentration to low concentration. Eventually the particles will be uniformly and randomly distributed.
What is the process that moves particles from areas of higher concentration?
The answer is is OSMOSIS the spontaneous net movement of water across a membrane from a region of low concentration to a solution with a high concentration, down a solute concentration gradient.
Which process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy?
passive transport (e2020 answer)
How do particles move from areas from lower concentration to areas of higher concentration?
The answer is is OSMOSIS the spontaneous net movement of water across a membrane from a region of low concentration to a solution with a high concentration, down a solute concentration gradient.
What is osmosis and reverse osmosis?
Osmosis is the passive movement of particles from an area of high concentration to an area of low concentration across a partially permeable membrane. reverse osmosis is the opposite?
What makes the cell membrane selective permeable?
A cell membrane is selectively permeable because it only allows particles to move across them due to different concentrations. Molecules move from areas of low concentration to high concentration.
When particles are moves through a membrane from a region of high concentration to a region of low concentration?
Diffusion
In diffiusion movement of particles across a membrane is drven by what differences?
In diffusion, the movement of particles across a membrane is driven by an electrochemical gradient-the ion's concentration gradient and the membrane potential. Substances will passively diffuse down their concentration gradient to where they are less concentrated. Since the inside of a cell is negative compared to its outside, the membrane potential will drive the passive transport of cations into the cell and anions out of the cell due to electrostatic attractions.
Which term describes the movement of water molecules into and out of the cell?
Osmosis is the movement of water particles from an area of high concentration to an area of low concentration, across a semi-permeable membrane.
