Relationship Between Cell Structure & Function
The relationship between the parts of a cell and their functions is exemplified with elegance and clarity in the organelles of eukaryotes.
In turn, all organelles feature a plasma membrane. Every plasma membrane in cells — including the outer, named cell membrane as well as the membranes enclosing organelles — consists of a phospholipidbilayer.
This bilayer consists of two individual "sheets" facing each other in a mirror-image fashion.
The inside features the hydrophobic, or water-repelling, portions of each layer, which consist of lipids in the form of fatty acids. The outer portions, in contrast, are hydrophilic, or water-seeking, and consist of the phosphate portions of the phospholipid molecules.
Thus one "wall" of hydrophilic phosphate heads faces the inside of the organelle (or in the case of the cell membrane per se, the cytoplasm) whereas the other faces the exterior, or cytoplasmic, side (or in the case of the cell membrane, the outside environment).
The structure of the membrane is such that small molecules
