What else can I help you with?
What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.
What is the term for a membrane that allows certain but not all molecules to diffuse through it?
semi-permeable.
A type of membrane which allows only certain molecules to pass through is called?
Semi- Permeable
What does it mean if a cell is selectively permiable?
The cell membrane only allows certain molecules through.
What is the term used for a layer that allows only certain molecules to pass through the cell membrane?
permiable
What is a material that allows certain molecules to pass through it called?
The Plasma Membrane, which has a phospholipid bi-layer.
What is a semipermeable mebrane?
The cell membrane is called as semi-permeable membrane because it allows only certain/selective molecules to pass through it.It mostly allows only solvent molecules to pass.It is sometimes also called as selectively permeable membrane.
What is meant by cell membrane is semipermeable?
It allows only certain molecules to pass through.
Why can't charged molecules pass through the membrane?
Charged molecules cannot pass through the membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through based on their size and charge. The charged molecules are repelled by the hydrophobic interior of the membrane, which prevents them from crossing.
Using an example explain what is meant by a partially permeable membrane?
A partially permeable membrane is a barrier that allows only certain substances to pass through while blocking others based on their size or properties. For example, a cell membrane is partially permeable because it allows water and small molecules to pass through while blocking larger molecules like proteins.
What is partly permeable?
A membrane, such as the cell membrane, which allows only certain types of molecules (usually small and non charged ones) to pass through it freeely.
How does diffusion occur through a semipermeable membrane?
Diffusion through a semipermeable membrane occurs when molecules move from an area of high concentration to an area of low concentration, passing through the membrane. This process is driven by the natural tendency of molecules to spread out and reach equilibrium. The semipermeable membrane allows only certain molecules to pass through based on their size and charge, regulating the movement of substances across the membrane.
