The total mass of the cell .the special importance of phospholipids and cholesterol in the cell is  highlighted  because they generally don't dissolve in water and therefore they form membrane  barriers separating the various compartments within the cell .Scientists have  divided the  cells into two groups.namely :the primordial cells, as. it is  evident from the previous  figure that the eukaryotic cells are larger than the prokaryotic cells and their size  may  exceed  a hundred times.cells are the basic units  of all living things.they  come in different shapes and sizes.it  also differs  based  on the function it performs in living creaturesAll cells  share  a morphological characteristics, the cell membrane ,as in the following figureThe cell membrane is a special barriers that helps control what  goes  into  and out of the cell.cells usually have a number of  common function .in addition to phospholipids and cholesterol , somes cells contain large amounts of triglycerides  called neutralizing lipids.the proportion of triglycerides in fat cells is about 95% by mass .usually,a small amount of sugars  are  stored in cells in the  form of glycogen which is an insoluble  polymer of  glucose that can be used in the cells to generate energy in them
The basic types of hive .Polysaccharides:  carbohydrates generally have  few  anabolic function in the cell , except for being part of the glycoprotein molecules.However, sugars  are always present  as glucose in the extracellular fluid surrounding cells and are  readii available for use in  cells .The fat stored  in these cells represents  the body's main store of energy- generating nutrients, which can  be analyzed and  used  when the body   needs energy.Most of the cells in the human body don't maintain large stores  of  sugars The sugar reserve  in it may  reach  only 1% of it's  total mass ,but  this reserve increases to 3% in muscle  cells ,and  sometimes this reserve reaches 6% in liver cells .cells also  break down molecules to  produce the energy needed for metabolismThe cell membrane is a special barriers that helps control what  goes  into  and out of the cell.cells usually have a number of  common function .for example, all cells contain genetic material that gives information and instructions to the cell to produce the materials it needs.for example, all cells contain genetic material that gives information and instructions to the cell to produce the materials it needs.cells also  break down molecules to  produce the energy needed for metabolism .but it plays a major role in nourishing the cell.
