The cell on the left is going through mitosis and its DNA has condensed. In biology, cell theory is a scientific theory which describes the properties of cells. These cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century.
The cell (from Latin cella, meaning small room) is the basic structural, functional, and biological unit of all known living organisms. Cells are the smallest unit of life that can replicate independently, and are often called the building blocks of life. The study of cells is called cell biology. Some eukaryotic cells (plant cells and fungal cells) also have a cell wall. 2  Inside the cell is the cytoplasmic region that contains the genome (DNA), ribosomes and various sorts of inclusions. 3  The genetic material is freely found in the cytoplasm.
