The study of cells or cell biology is called cytology. It is derived from the Greek word “kytos”, meaning vessel.
The cell is called as a fundamental unit of life because every single living species is composed of a cell.
The cell is a Latin word which refers to a small room. It was first discovered in the year 1665 by the English philosopher and architect named Robert Hooke. Later in the year 1839, two German Scientists, Matthias Schleiden and Theodor Schwann proposed the cell theory.
Cytology or cell biology is about the cell, cell division and its functions. Every living species are composed of a cell. A human body comprises around billion to trillion cells, which are mainly involved in different specialized functions. Their shape and size usually vary, and a single, minute cell alone can perform several functions to keep an organism healthy and alive.
Cytology the sub-discipline of biology, mainly deals with the study of the cell, cell theory, different types of cell- unicellular, multicellular, cell organelles along with their functions, prokaryotes, eukaryotes, and different kinds of cellular process.
