CELL : THE FUNCTIONAL UNIT OF LIFE
------------------------------------------------
The cells are known as building blocks or basic structural unit of life. As the blocks can be joined in many ways to make the building of different shapes and sizes. In same way all living organisms are made differently of different shapes, sizes and by different number of cells.
The cells were discovered by ROBERT HOOKE , a English scientist with his home made crude microscope he examined a thin slice of Cork and observed that it had comb like structure. he called these thick walled room like structures CELLS .
DEFINITION :- A unit mass of protoplasm with different , shape , size surrounded by a plasma membrane.
Some living organisms are made up of single cell, called UNICELLULAR ORGANISMS.
e.g :- amoeba, paramoecium and bacteria.
Most of the organisms are made of many cells called MULTICELLULAR ORGANISMS.
e.g :- Man , cat, mushrooms etc.
There are millions of living organisms. They are of different shapes and sizes. Their organs also vary in shape, size,and number of cells.
cells → Tissues → Organs → Organ system → Organisms.

The cell is the basic building block of a living organism. The cells were discovered by Robert Hooke who examined a cork under a microscope and he saw a honey comb like structure. He gave it a name ‘cell' Different cells perform different functions and they together form a living being. Some living beings consist of a single cell. Such organisms are called unicellular organisms ex. amoeba,Paramecium The structure of an organism depends upon the assembling of the cells. Hence the cells are the structural and functional unit of a cell....
