The membrane acts as a barrier that prevents most things from entering. Small molecules and water can diffuse across the membrane but most proteins and larger molecules cannot. The cell can use this advantage in combination with proteins to decide what gets in, what goes out and when that should happen.

What is the ability of a cell membrane to allow material to pass through it called?
permeability
What is the characteristic of a sell membrane that controls which substances can enter and exit the cell?
The selective permeability, also called semi-permeability, of the membrane controls which substances cant enter and exit the cell.
What is a Property of a membrane that allows some substances to move into and out of the cell?
semi- or selective permeability
What is the cell membrane that allows things to pass through?
It is called semi-permeability, a series of biochemical structures and processes that Control The Ingress and Egress of bio-materials into and out of The Cell.
What is the property of the cell membrane that allows only some materials to pass through it?
selectively permeable or selective permeability
What is the ability of a cell membrane to allow material to pass through it called?
permeability
How does the structure of the cell's membrane help the cells regulate water?
The semi-permeability of the cell membrane regulate water movement by osmosis.

semi- or selective permeability
What is membrane permeability?
Membrane permeability refers to the ability of molecules, substances, etc. to pass through the membrane. For example, the cell membrane is referred to as 'semi-permeable' because it allows some molecules (such as water) to enter, and stops other molecules (such as sodium ions) from passing through the membrane. If these want to get into the cell, they must then rely on proteins in the cell membrane to let them in.
What term is used to describe how the cell selects what materials enter and leave the cell?
selectively permeable or differentially permeable membrane
What is the cell membrane that allows things to pass through?
It is called semi-permeability, a series of biochemical structures and processes that Control The Ingress and Egress of bio-materials into and out of The Cell.
What structure allows only certain things to pass in and out of a cell?
The cell membrane. It is a semi-permeable membrane (or selectively permeable membrane) - this means that it only lets certain certain molecules or ions pass in or out of the cell. Permeability may depend on the molecule's size, solubility, properties, or chemistry.
Which organelle has a semi permeable membrane and separates the cell from it's environment?
The cell membrane (or plasma membrane) shows semi-permeability. In short some substances, such as gases and small electrically-neutral molecules CAN pass, while others like glucose and other large polar molecules CANNOT pass. Although glucose and other large polar molecules cannot pass through the semi-permeable cell membrane, they may enter through the interior of transport proteins.
What is the property of the cell membrane that allows only some materials to pass through it?
selectively permeable or selective permeability
Which part of a cell allows substances to pass through it?
The cell membrane, which encloses the cell, is a selective membrane which allows some molecules to pass and others not.
What is the plasma membrane function that keeps materials outside the cell from going inside?
The characteristic that a plasma membrane bears is the semi-permeability. This is what keeps certain materials in while keeping certain materials out.
