Summary Introduction
To discuss: The functions of the nucleus in eukaryotes.
Introduction: All life forms are formed of cells. Cells are very small to be seen with the naked eye. The size of a cell ranges from 1 µm to 100 µm in diameter. Robert Hooke was the first person to observe the cells under a microscope during 1665. He also coined the term “cell”.
