Prokaryotes are unicellular organisms that lack membrane-bound structures. This article details the structure of prokaryotic cells and provides examples of prokaryotic organisms.

The cell is the structural and functional unit of living organisms. It was discovered by Robert Hooke in 1665.

For life to function, cell membranes must remain intact. When these fragile barriers are damaged—for instance by heat or ...

These walls consist mainly of cellulose, noncellulosic polysaccharides and lignin, in proportions that depend upon the specific functions of the cell and its stage of development.

Our cells produce a variety of proteins, each with a specific role that, in many cases, means that they need to be in a ...

Researchers have developed artificial cell-like structures using inorganic matter that autonomously ingest, process, and push out material - recreating an essential function of living cells.

Harvard scientists studying the molecular structure of cells under obesity-related stress have spotted alterations in the architecture that can be patched up, with "striking" results that restore ...
