Centre of the Cell online; The Image & Video Library of The American Society for Cell Biology Archived 2011-06-10 at the Wayback Machine, a collection of peer-reviewed still images, video clips and digital books that illustrate the structure, function and biology of the cell.
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
Artist impression of cell components. The exact components of a cell are determined by whether the cell is a eukaryote or prokaryote. [7] Nucleus (eukaryotic only): storage of genetic material; control center of the cell. Cytosol: component of the cytoplasm consisting of jelly-like fluid in which organelles are suspended within; Cell membrane ...
The received wisdom said we were built from around 200 types of cell – such as heart muscle or nerve cells. Instead the Human Cell Atlas project has revealed there are thousands of cell types ...
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...

The work is part of the ongoing Human Cell Atlas project that was begun in 2016 and involves researchers around the world. The human body comprises roughly 37 trillion cells, with each cell type ...
On 2021, Stephen Quake guessed that the upper limit of the number of human cell types would be around 6000, based on a reasoning that "if biologists had discovered only 5% of cell types in the human body, then the upper limit of cell types to discover is somewhere around 6000 (i.e., 300/0.05)." [10] Other different efforts have used different ...
