What is the need for a semi permeable membrane?
A semi-permeable membrane allows only certain molecules or ions to pass through based on size or charge. This property is important for processes like osmosis, filtration, and dialysis, where selective transport of substances is required. It helps maintain balance and regulate concentrations of solutes in a system.
Definition of freely permeable membrane?
A freely permeable membrane allows all molecules or ions to pass through it without any hindrance. This means that there are no restrictions on the movement of substances across the membrane, and it is completely permeable to all solutes.
What is the difference between a semi-permeable and a partially permeable membrane?
An impermeable membrane is that through which no substance can pass. Semipermeable membranes are those that let only solvents, like water, to pass through it. Permeable membranes are those that let solvent and solutes, like ions and molecules, to pass across it. There are also selectively permeable membranes, i.e., membranes that besides allowing the passage of solvent, let only some specific solutes to pass while blocking others. See link:
What is moving across a semi permeable membrane during osmosis?
Water molecules move across a semi-permeable membrane during osmosis. This process occurs from an area of high water concentration to an area of low water concentration in order to equalize the concentration of solutes on both sides of the membrane.
What part of the cell does osmosis occur?
it occurs in the cell membrane(through the cell membrane really)

What involves the movement of solutes across a selectively permeable membrane by the process of difussion?
Osmosis involves the movement of solutes across a selectively permeable membrane by the process of diffusion. In osmosis, water molecules move across the membrane from an area of low solute concentration to an area of high solute concentration in order to equalize the concentration on both sides of the membrane.
What does a selectively permeable membrane have to do with osmosis?
A selectively permeable membrane allows only certain substances to pass through it while blocking others. In the context of osmosis, this membrane controls the movement of water molecules, allowing water to pass through freely while restricting the movement of solute particles based on their size and charge. This selective permeability is essential for maintaining the balance of water and solutes across a cell membrane.
Why the water molecules involves in osmosis?
Water molecules are involved in osmosis because they can move across a semi-permeable membrane to equalize the concentration of solutes on either side of the membrane. This movement of water is driven by the concentration gradient of solutes, resulting in changes in the volume of the compartments on either side of the membrane.
What is selecticely permeable?
Selective permeability usually refers to the ability of a membrane to regulate the movement of materials. An intervening membrane can physically prevent a solute from diffusing down its concentration gradient. This allows cells, for example, to maintain a cytoplasm with a different composition than the extra-cellular fluid. A membrane may contain protein channels for the passive diffusion of a specific substance, actively acquire or discharge others, and have no channels to facilitate the movement of another. Thus, the membrane is selectively permeable for different solutes, usually depending on the needs of the cell.

Will osmotic pressure be generated if solutes are able to diffuse?
Yes, osmotic pressure can still be generated even if solutes are able to diffuse. Osmotic pressure is a result of the concentration gradient of solute particles across a semipermeable membrane, and it is not affected by the ability of solutes to diffuse.
What part of the cell involves osmosis?
Osmosis primarily occurs in the cell membrane, which is selectively permeable, allowing water molecules to move across the membrane to maintain the cell's internal balance of solutes. Osmosis is crucial for maintaining proper hydration levels and regulating the concentration of solutes inside the cell.
Which the two structure in plant cell are selectively permeable allowing molecules of water and small solutes to pass through but preventing the passage of large solute molecule?
Cell membrane and sap vacuole membrane
