The cell is the basic functioning unit of organisms in which chemical reactions take place. These reactions involve an energy release needed to support life and build structures. The cell consists of membrane bound organelles‚ which are responsible for the division of labour. There are two main classes of cells- Prokaryotes which are cells without a nucleus‚ where the DNA is spread around the cytoplasm of the cell‚ an example of a prokaryote is a bacterium (See Figure 1). The other class is the Eukaryotes
