they can function as gates, channels, or pores. in doing so, they can have a specific affinity for a certain particle, and only allow that particle to go in. or in the case of pores, they are always open, but only allow certain size particles to flow through.
proteins can also couple with an enzyme, such as ATPase, to function in active transport, in which they transfer ions or particles against a concentration gradient and thus give the membrane an electrochemical potential gradient that the cell can use for work

Why is the plasma membrane selectively permeable?
The plasma membrane is selectively permeable because it needs to allow certain things in and certain things out.The plasma membrane is a selectively permeable membrane as it allows the entry and exit of some selected substances only.
Why is the plasma membrane called the semipermeable membrane?
the cell membrane allows only certain substances to pass through it It is considered semipermeable because, it allows non charged particals to pass through.
What cell part allows only certain substances to difuse into and out of the cell?
The cell's membrane allows only certain substances to diffuse in and out of the cell.
What do you understand by the semipermeability of the cell membrane?
it allows only certain required things and prevent foreign molecules which are harmful entering the cell.
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 a membrane called when only certain things can cross a membrane?
a membrane that only allows certain things to cross is called "selectively permeable"
What structure allows certain things to pass in and out of the cells?
The cell membrane allows only certain things to pass in and out of the cell.
What only allows certain substances in and out of a cell?
The permeability of the cell membrane controls which substances may pass in or out of the cell.
What stucture allows only certain things to pass in and out of the cell?
Cell membrane

A permeable membrane
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 is found in both plant and animal cells and allows only certain things to pass in and out of the cell?
cell membrane
What allows only certain substances into the cell?
The cell membrane.
What structure allows only certain things?
What structure allows only certain things to pass in And out of the cell
