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

The proteinshave certain 'identifiers' attached to them, which only allow certain particles through, making it selectively permeable.

Membrane proteins play a significant role in transporting only certain substances into the cell. They act as pores, channel or gates which allow substance to pass through in a selective manner.

The cell membrane sort of creates the vesicles in which the enzymes or proteins are transported. The cell membrane also has receptors with which it recognizes other vesicles which are in the interstial fluid ( the fluid between the tissues).
It is believed that carrier proteins bind their targets and escort them into the cell.
The Endoplasmic Reticlulum there is a soft and rough Endoplasmic Reticulum, another way to call the Endoplasmic Reticulum is called the ER.
Most membranes.
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.
the cell membrane allows only certain substances to pass through it It is considered semipermeable because, it allows non charged particals to pass through.
it allows only certain required things and prevent foreign molecules which are harmful entering the cell.
The cell's membrane allows only certain substances to diffuse in and out of the cell.
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.
a membrane that only allows certain things to cross is called "selectively permeable"
The cell membrane allows only certain things to pass in and out of the cell.
The permeability of the cell membrane controls which substances may pass in or out of the cell.

A permeable membrane
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.
