already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

Waste must be let out of the cell, while nutrients must be kept in. At the same time, nutrients must be let in, and toxins must be kept in.

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.

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

What is the function of the cell plasma membrane?

The cell membrane is the outermost barrier of an animal cell. As for plants, the cell membrane is surrounded by the cell wall, which gives the cell a much more rigid structure

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
