What is meant by cell membrane is semipermeable?
It allows only certain molecules to pass through.
What properties does a selective permeable membrane have?
the ability to allow materials to cross a membrane
Is the Visking tubing a partailly permeable membrane and why?
Yes, it is a partially permeable membrane. It allows certain substances like glucose and water molecules to diffuse through but not large molecules like starch and sucrose. Selectively permeable.
What does selective permeability mean what is responsible for the selective permeability of the plasma or cell membrane?
When a cell's membrane is permeable, it means that only certain proteins and other molecules can go in and out of the porous membrane, through protein pumps and other pathways. Some molecules stay inside the cell, while others float outside. Starches, for example, are large molecules that cannot pass through the membrane.
Using an example explain what is meant by a partially permeable membrane?
A membrane that allows some things to pass through it but not others. It can be to do with size of the molecule, electronic charge or other characteristics. Think of a sieve or colander as an example of the semi-permeable membrane and a mixture of sand and peas as the chemical mixture at one side of the membrane. The membrane will only allow the sand to pass through based on size. In cases such as this, larger molecules could pass through active transport channels and such that may be present on the membrane but these are energy-dependant whereas diffusion across a semi-permeable membrane is not.
What do you call a cell membrane that allows certain molecules to pass through?
A selectively permeable membrane.
What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.
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 the term for a membrane that allows certain but not all molecules to diffuse through it?
semi-permeable.
Why do you think that the eggs membrane will let water to enter but not corn syrup?
water molecules are smaller than corn syrup. the membrane allows a certain size of molecules.
What does it mean if a cell is selectively permiable?
The cell membrane only allows certain molecules through.
A type of membrane which allows only certain molecules to pass through is called?
Semi- Permeable
Cell membrane is semipermeable what doe that mean?
It allows only certain molecules to pass through.
What is a material that allows certain molecules to pass through it called?
The Plasma Membrane, which has a phospholipid bi-layer.
What is the term used for a layer that allows only certain molecules to pass through the cell membrane?
permiable
