The Discovery of the Cell

CELL FUNCTION


Pamela Conoly



Cells are the basic unit of structure of all living organisms, even viruses. Cells were

discovered by Robert Hooke in 1665. But Schleiden and Schwann were the first in

creating a theory in 1839. This theory stated that all living things were cellular.

The largest cells being egg cells and the smallest being mycoplasmas.


All cells contain DNA which controls cell activity. All cells also contain cytoplasm

containing organelles of various kinds and are surrounded by a plasma membrane.

This controls entry and exit of substances.


In multicellular organisms cells become specialized for different functions. This is

A division of labour. In the cell further division occurs between the organellas.

In theory

Theoretically speaking, how long do you think it would take,providing proper DNA, to perform cell division?Given that it was a virus.
