As the cell membrane only allows certain substances to enter or leave the cell, meaning that while it IS permeable (as some substances can cross it), it is only selectively as not all substances are able to cross it, only some.

A membrane that allows some substances to pass through while excluding others would be called a?

semipermeable or selectively permeable.


What is a membrane that allows some substances to pass through but excludes others?

A membrane that lets some substances pass through but not others is known as a semipermeable membrane. Other terms that describe this type of membrane are: selectively permeable, partially permeable, or differentially permeable.


What is a membrane called when only certain things can cross a membrane?

A membrane that only allows certain substances to cross is called a selectively permeable or semi-permeable membrane. It allows some molecules or ions to pass through while blocking others based on characteristics like size, charge, or solubility.


Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?

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.


Cell membranes that allow certain molecules to pass through while keeping others out are called?

semi permiable I believe, but I'm not 100 percent sure on the spelling selectively permeable


What process - movement of water across a selectively permeable membrane from an area of high water concentration to an area of low concentration?

Osmosis is the process by which water moves across a selectively permeable membrane.


What is it called that all cells have that allow them to let materials in and out?

selectively permeable membrane.


Why is the plasma membrane called the semipermeable membrane?

The plasma membrane is called the semipermeable membrane because it allows certain substances to pass through while restricting the passage of others. It is selectively permeable, meaning it controls the movement of substances in and out of the cell to maintain internal balance and regulate cellular processes.


What is it called when Water molecules move from higher concentration to lower concentration through a semipermeable or selectively permeable is called?

The process fo Osmosis.


The diffusion of water across a selectively permeable membrane through aquaporins is called?

osmosis


The passive transport of water across a selectively permeable is called?

The passive transport of water across a selectively permeable membrane is called osmosis. Osmosis involves the movement of water molecules from an area of higher concentration to an area of lower concentration, in order to equalize the solute concentrations on both sides of the membrane.


What is the movement of water through a selectively permeable membrane?

The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
