The cell is the building unit and the basic functional function of all living organisms, because each cell achieves the totality of life features.
In other words, the cell building is one of the characteristics of life. At the same time, the cell is the smallest building that achieves all the characteristics of life (reaction to stimulation, reproduction, growth and development, exchange of materials).
There are two types of cells with a nucleus:
1 - Eukaryotic: the nucleus is surrounded by a membrane (a nuclear membrane).
2 - Primitive nucleus (non-eukaryotic): The nuclei are not surrounded by a membrane (a nuclear membrane).
