*from latin cella, meaning “small room”*

*the cell is the basic [‘structural’/’functional’/’biological’ unit] of all known living ‘organisms’*
.
(a cell is the smallest unit of life that can replicate independently, and cells are often called the “building blocks of life”)
(the study of ‘cells’ is called ‘cell biology’)
(‘cells’ consist of ‘cytoplasm’ enclosed within a ‘membrane’, which contains many ‘biomolecules’ such as ‘proteins’ and ‘nucleic acids’)
(‘organisms’ can be classified as ‘unicellular’ (consisting of a single cell; including ‘bacteria’) or ‘multicellular’ (including ‘plants’ and ‘animals’))
(while the number of ‘cells’ in ‘plants’ and ‘animals’ varies from ‘species’ to ‘species’, ‘humans’ contain more than 10 trillion (1013) cells)
(most ‘plant’ and ‘animal’ cells are visible only under a ‘microscope’, with dimensions between ‘1’ and ‘100’ ‘micrometres’)
(the ‘cell’ was discovered by ‘robert hooke’ in 1665, who named the biological units for their resemblance to ‘cells’ inhabited by ‘christian monks’ in a ‘monastery’)
(‘cell theory’, first developed in 1839 by ‘matthias jakob schleiden’ and ‘theodor schwann’, states that all organisms are composed of 1 or more ‘cells’, that ‘cells’ are the fundamental unit of structure and function in all living organisms, that all cells come from preexisting cells, and that all cells contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation of cells)
.
(‘cells’ emerged on ‘earth’ at least ‘3.5 billion years ago’)
