What is the thin flexible barrier around the cell is called?

Answer 1

Cell wall

Answer 2

It is called aphospolipid bi-layer it is a bi-layer because i consist of two layers of phopholipids. One layer consists of a hydrophillic head (water loving) on the outside of the membrane and a hydrophobic (water hating) tail, this tail and head makes up a BILAYER. It also contains channel protein and protein carriers. This COMPOSITION OF phospolipid bi-layer is commonly known as ...THE CELL MEMBRANE.

Answer 3

The cell membrane divides the cell from its' surroundings. This membrane is called the fluid mosaic model as it is a mixture of phospholipids, cholesterol, proteins and carbohydrates.

Most of the membrane is composed of phospholipid molecules. These allow the membrane to

be rather fluid. Embedded in this membrane are proteins which give some structure to the membrane. The 3rd components are proteins or glycolipids.

The membrane can seal itself if pierced by something very thin like a pin. But it will

burst if it takes in too much water.

The proteins sort of float on the surface of the membrane like islands in the sea.

Cholesterol is also found in the membrane. It prevents lower temperatures from inhibiting

the fluidity of the membrane and prevents higher temperatures from increasing fluidity.

Cholesterol is only found in animal cells.

The carbohydrates that are in plasma membranes are bound either to proteins or to the

lipids. They form sites on the surface that allow the cells to recognize each other.

This is important because it tells the immune system to determine whether a cell is foreign (non-self) or are body cells (self).

Answer 4

The thin flexible barrier around the cell is called the cell membrane. It controls the movement of substances in and out of the cell, helping to maintain the cell's internal environment and protect it from the external environment.

Answer 5

The cell membrane

Answer 6

A cell membrane.

Answer 7

cell membrane

Answer 8

Cell Membrane
