The main cellular structures of a living cell and characterize their functions.

The structure of any cell is distinguished by various organelles. It all depends on its function, type of organism, kingdom. The most important structure of most cells is the nucleus. It contains all the genetic information about the structure and synthesis of all cell structures, their reproduction. Also, the nucleus is necessary for cell division. But not all cells have it. For example, human red blood cells lack a nucleus and many other structures. Ribosomes are important structures. They are responsible for the synthesis of protein structures during replication.
