A cell is the basic unit of an organism. Every living thing in the universe is made up of cells. The shape, size and number of cells vary in different organisms and their different organs. Unicellular organisms are the only cells that make up the body. (E.g. amoeba) When multicellular organisms form a body together with more than one cell. The anatomical and functional unit of the living body is called the cell.
The word cell is derived from the Latin word 'cellula'. Which means 'small room'. Robert Hooke (England) The first cell was seen by Robert Hooke in 1665. Robert Hooke was appointed curator of the newly established Royal Society's experiment in 1662. He designed the Gregorian reflective telescope. Discovered the fifth star in the Trapezium, as well as one constellation in the Orion constellation, and suggested that Gar orbits on its own axis. Among the physicists, Robert Hooke was most famous for his discovery of the law of positional foundations. The English scientist Robert Hooke (1665) took a thin cut of a beech made of a plant called 'oak' (cork) and looked at it under a microscope. Levonhawk first saw living cells in 1674. He studied bacterial cells under a microscope. In 1881, a scientist named Robert Brown discovered the cell nucleus in a cell. The scientist Perkinze named the living matter in the cell Jivaras. German scientists M. Schleiden and Schwann introduced cellism in 1839. There are an estimated 100 trillion (10) cells in the human body. Organisms vary greatly in their color, shape, and shape. In the same way diversity is found in their cells. The branch of biology that studies cells is called cytology or cell biology. Based on the number of cells in an organism, the classification of organisms can be divided into two main types: 1) Unicellular organisms which have only one cell are called unicellular organisms. E.g. Chlamydomonas (Lila), Bacterial parasites - Amoeba, Paramecium, Euglena, Plasmodium 2) Multicellular organisms The body of a multicellular organism is called a cell that is made up of more than one cell. E.g. Animals, birds, insects, et
