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

Eukaryotic cells form the foundation of complex life, their defining feature being the presence of membrane-bound organelles. This article details the structure of eukaryotic cells and provides ...

Plant cells have some specialized properties that make them distinct from animal cells. Learn how special structures, such as chloroplasts and cell walls, create this distinction.

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

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.

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

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

Linking RNA structure and function Date: September 9, 2016 Source: Massachusetts Institute of Technology Summary: Several years ago, biologists discovered a new type of genetic material known as ...

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 ...

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.
