Why are plasma membranes described as differentially permeable?

Plasma membranes are described as being differentially permeable because they select what substances can pass through and what can not. Their behaviour is different for each s

Are plasma membranes selective barriers?

Yes because cells only let certain substances to cross the plama membrane using either passive transport or active transport

Describe how cell membranes are selectively permeable?

Cell membranes are selectively permeable because it allows some things to enter or leave the cell while keeping other things outside or inside the cell.

What makes the cell membrane selectively permeable?

A cell membrane is selectively permeable because it only allows  particles to move across them due to different concentrations.  Molecules move from areas of low concentrati

What is the function of a selectively permeable membrane?

selectivley permeable membranes only allow certain materials to  pass through.   It allows some molecules to enter the cell and blocks entry to  others.

What is the effect of a selectively permeable membrane in osmosis?

A selectively permeable membrane (also known as a differentially permeable membrane or a semi-permeable membrane) is permeable to the solvent but not to solutes. In cells, t

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 i

What is meant by the cell plasma membrane being selectively permeable?

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

Why is the cell membrane selectively permeable?

The cell needs to control what enters and leaves. It needs to keep somethings in and other things out. However, only the Selectively cells can enter and go out of the cell! Th

Why is a cell membrane selectively permeable?

it´s selectively permeable because some substances can pass across the membrane and others cannot, and it´s always trying to keep the proper amount of water and nutrients in

In what way are cell membranes selectively permeable?

  The cell membrane (also called the plasma membrane, plasmalemma, or "phospholipid bilayer") is a selectively permeable lipid bilayer found in all cells. It contains a wi
