     INTRODUCTION

Cell is the fundamental of life. 

Our body are made up of cells. without cells life is not possible. 

ROBERT HOOK is the father of  cell ( cytology- study of cell are known as the cytology)

Robert hook discovered a dead cell from quark. 

second discovery of cell is done by ANTONIE VON LAVOUISIER . He found a living cells in water. 

Now he tell that room like portion is present in the cell. 

After this discovery many scientist come out aand give a cell theory.

Now  Famous scientist was come SHWAN AND SCHLIDEN . He gave a modern cell theory.

Which means he say that 

                ('omnis cellula e cellula' )

'A cell is made from pre existing cell '

But after some time this theory is failed.

TYPES OF CELL

There are two types of cells.

(1). Eukaryotic cells 

(2). prokaryotic  cells 

EUKARYOTIC CELL 

This types of cells have  well find nucleus. 

This types of cells have plasma membrane 

This types of cells have vacuoles 

This types of cells is found in kingdom plantae and animalia

This types of cells have well cell wall .

PROKARYOTIC CELL

This types of cells have not defined nucleus.

This types of cells have not plasma membrane 

This types of cells have not vacuoles 

This types ofts cells are found in kingdom monera , protista, fungi. 

This types of cells have not cell wall.

PLANT CELLS 

These are those cells which is found   in plants 

In plants cell wall is present 

In plant cell membrane is absent 

In plant endoplasmic reticulum is absent 

In plant lysosome is absent

ANIMAL CELL 

In animal cell cellmembrane is present 

In animal cell cell wall is absent 

In animal cell  endoplasmic reticulum is present 

In animal cell  lysome is present
