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.
The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells [13] All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. [14] The activity of an organism depends on the total activity of independent ...
Thomas began writing a monthly essay “Notes of a Biology Watcher” in the New England Journal of Medicine in 1971 while he was at Yale. In 1973 he became the president of the Sloan-Kettering Institute in New York. Lewis Thomas published multiple books throughout his career, the first being The Lives of a Cell: Notes of a Biology Watcher.
The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
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 ...
Cells are the structural and functional units of life. [1] The smallest organisms are single cells, while the largest organisms are assemblages of trillions of cells. DNA, double stranded macromolecule that carries the hereditary information of the cell [2] and found in all living cells; [3] each cell carries chromosome(s) having a distinctive ...

Cells are the basic unit of structure in every living thing, and all cells arise from pre-existing cells by division. [ 137 ] [ 138 ] Cell theory was formulated by Henri Dutrochet , Theodor Schwann , Rudolf Virchow and others during the early nineteenth century, and subsequently became widely accepted. [ 139 ]
