. It is applicable to almost all living organisms and it incorporates nearly all the modern findings about cells. In unicellular organisms, the single cell that comprises the body leads a totally autonomous existance. The various cell organelles perform the vital body functions...
Unit Membrane Concept
The molecular structure of cell membrane is still not clearly known. Several models have been proposed from time to time to explain its structure based on its physico-chemical properties. In the year 1935 Danielli and Dawson proposed that the cell membrane is made up of a lipid layer sandwiched bet..
