What is the building unit of living beings? What is it called and who gave it that name?

The basis of the structure of all living organisms is the cell. It is an elementary system that has its own metabolism and is capable of living separately from other cells. Has the ability to form new cells by division.

The science that studies cells, their structure and vital activity is called cytology. The cells were discovered by scientists at the beginning of the second half of the seventeenth century. The Englishman examined a cut of a tree under a microscope and discovered a huge number of cells, which he gave the name – cells.
