AN INTRODUCTION TO CELL BIOLOGY (BRIEF HISTORY OF CYTOLOGY)

Cell Biology (Gr., kytos-hollow vessel or cell, logos-to discourse) is a biological science which deals with the study of cells. The cell itself can be regarded as the vital unit of organisms. 'Aristotle' and 'Paracelsus' concluded that "all animals and plants, however, complicated are constituted by few elements which are repeated in each one of them."
