WebView history. Tools. Cell theory has its origins in seventeenth century microscopy observations, but it was nearly two hundred years before a complete cell membrane theory was developed to explain what separates cells from the outside world. By the 19th century it was accepted that some form of semi-permeable barrier must exist around a cell. WebThe cytoplasm is bounded on the outer side by a delicate, flexible, thin layer called the plasma lemma or ectoplast. It is 75-100 Å thick. Likewise to the inner side it is bounded by another membrane said as tonoplast which is 75-100 Å thick. The main function of cell membrane is to regulate the transfer of materials inside and outside of the ...
