a dialysis membrane is selectively permeable, it is used in experiments to simulate cellular membranes, and it is permeable to water but not to sucrose.
The dialysis membrane is selectively permeable because it doesn't allow all cells to go through it. Think of it as a kidney. When blood is sent to the kidney, the blood cells cannot fit through the dialysis inside the kidney, but the waste and bacteria in the cells do. So, The dialysis membrane is selectively permeable.
tubing made of selectively permeable membrane
A semi-permeable membrane. It could be compared to dialysis tubing.
semipermeable or selectively permeable.
Dialysis tubing can model a selectively permeable membrane by allowing certain small molecules and ions to pass through while restricting larger molecules. When filled with a solution and submerged in another solution, the tubing will permit the diffusion of substances like water, glucose, and ions based on concentration gradients. This setup effectively demonstrates principles of osmosis and diffusion, illustrating how cells selectively allow materials in and out. By observing changes in mass or concentration, one can visualize the behavior of a selectively permeable membrane in biological systems.
Artificial membranes in a dialysis machine are selectively permeable because it doesn't all cells to go through it. It doesn't allow blood cells to fit through the dialysis but it allows waste and bacteria to pass.
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
no
Cell membranes are indeed selectively permeable.
A selectively permeable membrane allows some substances through it and does not allow others.Allows certain substances to pass but not others
The selectively permeable phospholipid bilayer (a.k.a plasma membrane) is 'selectively permeable' because it selects which molecules it allows to permeate (pass through).
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
