The outer layer of the cell is the cell membrane. This membrane is made up of phospholipids which themselves are made of a polar phosphate head and a non-polar fatty acid tail. The polar heads face the exterior and interior of the cell while the fatty acid tails comprise the interior of the membrane that is created by this arrangement. The membrane acts like a "gatekeeper" for 2 reasons:
1) water and ions can diffuse freely across the membrane while larger molecules cannot
2) a vast variety of proteins are embedded in the membrane and they allow certain ions and even larger molecules to flow to the interior of the cell.
This "gatekeeper" function is important for maintaining the cells internal activities.

What is the outer layer of a prokaryote cell called?
slime layer
What is the job for cell membrane?
The job for cell membrane is to provide mechanical support
Thick outer covering of a plant cell?
the cell wall is a rigid outer layer unique to plant cells. it shapes and protects the cell, unlike animal cells, whose outer most layer is the plasma membrane (a layer that lies beneath the cell wall in plant cells)
What are the outer layer of a human red blood cell?
The outer layer of an animal cell is called the cell membrane. It controls what can go into and come out of the cell.
What is the outer edge of an animal cell called?
The outside layer of the animal cell is the cell membrane.

Plasma membrane
What is the outer layer of a cell that acts as a gatekeeper to a cell?
Cell Membrane
What is the stiff outer layer that surrounds the outer layer of the cell membrane?
cell membrane
What is the outer layer of a cell that selects what comes in and out?
The outer layer of the cell that controles what goes in and out is the cell wall. Cell wall acts like a security guard because security guards control what goes in and out i think but if this isn't right think of a state boarder.
Where is a cell membrane found in?
In a plant cell it is located just inside of the cell wall (outer layer). In an animal cell, the cell membrane is the outer layer.

What floats around the cell membrane?
well in a persons body its blood because the cell membrane is the outer layer for a cell but in a plant it isn't the outer layer
What is a cell mebrain?
Outer layer of the cell used to protect it.
Where does squamous cell carcinoma occurs in what layer of the skin?
outer layer
Where are cell membrane found?
on the outer layer of the cell ----------------------------------------- The membrane is found around the edge of a cell - it encases the cell and controls what goes in and out of it. In plants, the membrane is protected by a thick cell wall.
