The plasma membrane is selectively permeable, allowing certain molecules to travel in and out of the cell. The size, PH, and temperature all play a factor in what molecules travel through the membrane or don't.

A membrane at the boundry of every cell that acts as a selective barrier?

The cell membrane is a phospholipid bilayer that acts as a selective barrier, controlling the passage of molecules into and out of the cell. It helps maintain cellular homeostasis by regulating the entry and exit of substances such as ions, nutrients, and waste products.

What is the roll of the cellmembrane?

It protects the cell from outside forces. The cell membrane works as a selective filter that allows only certain things to come inside or go outside the cell.


What is the major component of a typical animal cell determines structure and function?

The cell membrane is a major component of an animal cell that determines its structure and function. It acts as a protective barrier, regulates the passage of substances in and out of the cell, and plays a key role in cell communication and signaling.

How are lipids suited to the functions of the membrane?

the outer boundary of the cell. It separates the cell from its surroundings and acts as a selective barrier to the passage of substances in and out of the cell.


What is a selective barrier regulating the passage of materials into and out of the cell?

In a plant cell, this selective barrier is known as the cell membrane but also a plant cell has a cell wall. The cell membrane is semi permeable allowing only certain materials so the cell membrane allows in materials and the cell wall ''digests it''. While in a plant cell does not have a cell wall only a cell membrane.It is the cell membrane that acts as its selective barrier.


This structure is the outermost boundary of the cell and is semipermeable?

The structure you are referring to is the cell membrane, also known as the plasma membrane. It surrounds the cell, acts as a barrier, and regulates the passage of substances in and out of the cell through selective permeability.


What structure holds the cell together?

The cell membrane is the structure that holds the cell together. It acts as a barrier between the cell's interior and its surrounding environment, allowing for selective transport of molecules in and out of the cell. Additionally, the cell membrane is involved in cell signaling and communication with neighboring cells.
