Question

concepts
Il living beings, whether plants or animals, are made
up of cells. A cell is the base structural and
functional unit of a living organism.
Any function performed by an organism is due to the
activity of the cells in its body. For example, it is the cells

food by utilizing sunlight, carbon dioxide

of its muscle cells to contract and relax,
A cell can live independently on its own and perform all
the life processes. This is why cells are called the building
blocks of life. Cells are very minute and cannot be seen by
the naked eye. You need a microscope to see them,
Discovery of the cell
Cells were not discovered until the invention of the
microscope. The Dutch scientist Anton Van Leeuwenhoek
(1632-1723) developed the first simple microscope, It was
made up of a single lens (Fig. 3.1). The use of this microscope
enabled him to see blood cells in the capillaries of the webbed
foot of a frog. He also observed tiny single-celled organisms in
a drop of water. Leeuwenhoek was the first to recognize these
organisms as living units of living beings. However, he did not
call them cells.
Robert Hooke (1635–1703), an English scientist, used
two lenses to devise a compound microscope (Fig. 3.3). He
studied a thin slice of cork under his microscope and observed
small box-like structures in it. He called them 'cells (Fig. 3.4).
The word 'cell' is derived from the Latin word 'cellula",
meaning ‘small compartment. Thus, cell was discovered and
named for the first time by Robert Hooke in 1665. Cork is
