Answer:
cells are the basic structural and functional unit of life.
the word cell is derived from the Latin word cellula which means a little room or a prison room.
the cell consists of a cell wall, a cell membrane, organelles such as the mitochondria, golgi bodies, endoplasmic reticulum 1. smooth endoplasmic reticulum 2. rough endoplasmic. the cells also contains a jelly like substance called as the cytoplasm in which all the cellular components are generally suspended.
the control centre of the cell is known as the nucleus- it is located at the centre of the cell and controls all the metabolic activities of the cell.
the cells were first discovered by a scientist called as ROBERT HOOKE- he observed the cork of the cell, what he observed was only the cell walls because there was no living protoplasm in the dead bark of the cell.
ROBERT HOOKE observed the cells under his hand made microscope or his primitive microscope.
he noted down all his observations in his book called as the MICROGRAPHIA in 1665
Next in 1673 Anthon con leewenhooke observed the living cells in the roots of an orchid root. hence he is often known as the FATHER OF MICROBIOLOGY.
Anthon von leewenhook discovered the tuberculosis bacteria. he was a lens maker from the occupation.
in 1831 ROBERT BROWN discovered the nucleus.
In 1838 and 1839 children and Schwaan proposed the cell theory.
ROBERT VIRCHOW said _ omnis cellular e cellulae which means all the cells arise from the pre existing cells.
