To know about a cell, its history, structure and functions is where the serious study of biology as a subject starts. So, it is necessary to remember that cell was first discovered by Robert Hooke in 1665. Even he did not fully know what he had discovered. The importance and understanding was taken seriously only after the cell theory was formulated by Matthias Jakob Schleiden and Theodor Schwann in 1839.
If you are planning to take up medicine as a career option, I would suggest that you start taking up biology seriously from now onwards.
