what conditions are necessary for osmosis to take place?

Answer: conditions required for osmosis are: presence of a concentration gradient ,the solution separated by a semi permieable membrane should have different concentration. presence of a semi permeable membrane.

Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. ... Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.

The best statement that accurately describes osmosis is: Osmosis is the diffusion of water across a membrane.

The osmotic pressure of a solution is the pressure difference needed to stop the flow of solvent across a semipermeable membrane. The osmotic pressure of a solution is proportional to the molar concentration of the solute particles in solution. MM is the molar mass of the solute.

Osmosis is the special case of diffusion involving water molecules. ... A selectively permeable membrane allows small, soluble molecules to pass through it, but prevents large insoluble molecules from passing through.

Osmosis is a special type of diffusion and can only be used to describe the movement of water molecules (as oppose to another type of molecule such as a gas). Osmosis occurs where there is a semi-permeable membrane which only allows water molecules through. ... This is the opposite direction to diffusion and osmosis.

Diffusion and osmosis are passive processes, meaning they don't need energy to occur. Both are spontaneous processes. ... In osmosis, water freely moves across a membrane from an area of low solute concentration, or hypotonic solution, to one of high solute concentration, or hypertonic solution.

Osmotic pressure is a hydrostatic pressure exerted to the solution to prevent the flow of water through the semi permeable membrane. This pressure is generally created by the solute present in the solution. ... Thus, the osmotic pressure of a solution will always be positive.

Direct link to Isabella Nicolè's post “"In osmosis, water moves from areas of low concent...” "In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute." ... So osmosis only occurs with a semipermeable membrane, and even with the membrane some water will move both sides.

Osmosis is the diffusion of a fluid through a semipermeable membrane. ... The osmotic pressure of a solution is the pressure difference needed to stop the flow of solvent across a semipermeable membrane. The osmotic pressure of a solution is proportional to the molar concentration of the solute particles in solution.

Cell membranes are semipermeable, which means molecules can move through them. ... Osmosis is where solvent molecules (usually water) move from one side of a cell membrane to the other. This happens because the concentration of a solute is higher on one side.

Osmosis. Osmosis is a term describing the movement of water from across a selectively permeable membrane as a result of a concentration gradient. I.e. it is a special type of diffusion concerned only with water. ... Osmosis is also a form of passive transport, as it does not require the expense of energy.

Effects of osmosis in plant cells When the plant cell is placed in a hypotonic solution, it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. ... When a plant cell is placed in an isotonic solution, a phenomenon called 'incipient plasmolysis' is said to occur.

Osmosis is the tendency for water molecules to move from where there is a higher concentration to where there is a lower one. Since cells have many other molecules inside of them, the tendency is for water to want to flow into the cell. ... The cell membrane helps to regulate and slow down the flow of water into the cell.

Osmoregulation and osmotic balance are important bodily functions, resulting in water and salt balance. ... Osmosis is the movement of water across the membrane. Osmosis occurs to equalize the number of solute molecules across a semi-permeable membrane by the movement of water to the side of higher solute concentration.

Osmosis is a passive transport. Traditionally, it is viewed as the movement of a solvent from an area of lower solute concentration to an area of...

Diffusion occurs in solids, liquids, and gases. A semipermeable ( partially permeable) membrane allows diffusion (and osmosis), but is not required.
