Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
1.2.6 Smooth muscle. 1.3 Neural tube. 1.3.1 Central nervous system. 1.3.2 Pineal gland. 2 Cells derived from mesoderm. ... List of human cell types derived from the ...
The main distinguishing feature of eukaryotes as compared to prokaryotes is compartmentalization: the presence of membrane-bound organelles (compartments) in which specific activities take place. Most important among these is a cell nucleus, [2] an organelle that houses the cell's DNA. This nucleus gives the eukaryote its name, which means ...
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 ...
Human Cell Atlas; Content; Description: The Human Cell Atlas is a global consortium that is creating detailed maps of the cells in the human body to transform understanding of health and disease. Organisms: Human: Contact; Primary citation: Regev, Aviv; et al. (Human Cell Atlas Organizing Committee) (2018). "The Human Cell Atlas White Paper".
The human body consists of biological systems, that consist of organs, that consist of tissues, that consist of cells and connective tissue. The history of anatomy has been characterized, over a long period of time, by a continually developing understanding of the functions of organs and structures in the body.
This Adobe SVG diagram is very large because its creator kept the superfluous Adobe PGF or other CDATA garbage The file size of this SVG diagram may be irrationally large because its text has been converted to paths inhibiting translations.
The cells of meristematic tissue are similar in structure and have a thin and elastic primary cell wall made of cellulose. They are compactly arranged without inter-cellular spaces between them. Each cell contains a dense cytoplasm and a prominent cell nucleus. The dense protoplasm of meristematic cells contains very few vacuoles.
