Why is the selective permeability of the plasma membrane essential for normal cell function?

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.

Why is the plasma membrane called a selectively permeable membrane?

The Plasma Membrane is a selectively permeable membrane as it only allows entry and exit of some selected molecules into and out of the Cells. It also prevents movement of s

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.

How are selectively permeable membranes essential for life?

Because they allow the passage of water, lipids, nutrients and ions into the cell while checking large molecules and larger polar molecules. These are controlled by transport

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 a selectively permeable membrane and how does it function?

It is a membrane in cells that only allows certain things in. For example a long time ago large and small cats had an epidemic of acquired immune deficiency syndrome (aids). a

Function of selectively permeable membrane?

It is selective about what can come in and out of the cell. An example of a Selectively Permeable membrane is a cell membrane.

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
