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.
Diffusion is the movement of particles from an area of high concentration to low concentration, while osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to high solute concentration.
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.
across semipermeable membrane? That is osmosis, the net movement of water.
During osmosis, water molecules move across a cell membrane from an area of low solute concentration to an area of high solute concentration in order to balance the concentration of solutes on both sides of the membrane. Diffusion involves the movement of molecules from an area of high concentration to an area of low concentration across the cell membrane until equilibrium is reached. Both processes are passive and do not require energy input from the cell.
Osmolarity is a measure of the concentration of solute particles in a solution. It is expressed in osmoles per liter and is used to calculate the number of particles in a solution, which influences processes like diffusion and osmosis across a semi-permeable membrane.
Active transport is the movement of particles across a cell membrane against the concentration gradient with the help of energy. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, and osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

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.
Osmosis involves a membrane. It is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration. Diffusion, on the other hand, is the movement of particles from an area of high concentration to an area of low concentration, and it can occur with or without a membrane.
In diffusion, movement of particles across a membrane is driven by differences in concentration gradients, which is the difference in concentration of a substance on either side of the membrane. Particles naturally move from areas of higher concentration to areas of lower concentration until equilibrium is reached.
When one area has a higher concentration than another area substances move from the area of high concentration to the area of low 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.
passive transport (e2020 answer)
Active transport is the mechanism by which particles are moved from areas of lower concentration to areas of higher concentration in a cell. This process requires energy to pump the particles across the cell membrane against their concentration gradient.
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.
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.
