what is the outer layer of a cell?

Answer 1

depends on the cell
plant- cell wall
animal- cell membrane

Answer 2

the outer layer depends on cell in plant the outer layer of cell is cell wall which protect the cell and in animals the outer layer is plasma membrane and cell wall is not present. though the plasma membrane also protect the cell but is less effective than cell wall. the plasma membrane is made of lipids and thus is useful for different kind of channels it also help in identification of organism by staining.

Answer 3

The outer layer of a cell would be the plasma membrane. The cell wall is the outside for plant cells, plasma membrane for non-plant cells. The plasma membrane, at least for people, is a phospholipid (phosphorus and fats) bilayer (2 layers). Glycoproteins (sugar and proteins) and cholesterols also help make it up.

Answer 4

I think the best answer is the plasma membrane because the plasma membrane contains the cytoplasm and regulates what goes into and out of the cell. Many cells have the cell wall surrounding the plasma membrane, but the cell wall does not keep many materials in or out, so it doesn't really seem like the outer limit of the cell.

Answer 5

well, there are two types of living cells.one type is the animal cell and the outer layer of animal cell is called the 'cell membrane'. this membrane seperates the protoplasm (cytoplasm+nucleus) of cell from the contents of other cells.this membrane is partially-permeable and the function is to protect the inner contents of the cell as well as to control the materials that enter inside the cell.it is semi-permeable so it allows only somethings to pass through but stop others.as far as the plant cells are concerned they consist of the outer layer called the 'cell wall'. this cell wall is made up of glucose and it also protects the inner parts of cell.this however is not semi-permeable and it encloses the cell-membrane similar to that of animal's.hope this is the answer.all the best.

Answer 6

In most cells the membrane is made up of a lipid bilayer. It is formed when phospholipids join together with the hydrophilic head facing out and the tails of the phospholipids(fatty acids) facing towards each other with the center filled with plasma and protien. One layer has the heads of the phospholipids facing towards the inside of the cell and the outer layer has the heads facing the outside of the cell. you can veiw examples at my anatomy and phys. text website. www.mhhe.com/saladin
