Revision Notes on The Fundamental Unit of Life

Quick Review

All living organisms in this universe are made up of cells.

They either exist as a single cell or as a combination of multiple cells.

Discoveries about Cells – The Fundamental Unit of Life

Discovered By Period of time What they discovered?

Robert Hooke 1665

noticed the presence of cells in a cork slice

Leeuwenhoek 1674

found the presence of living cells in the pond water

Robert Brown 1831

recognized the existence of a nucleus in the cell

Purkinje 1839

invented the term ‘Protoplasm’ which is the liquid present in a cell

Schleiden and Schwann 1838, 1839

presented the cell theory that all organisms are actually made up of cells

Virchow 1855

suggested that all cells come from cells that already exist in nature

The Cell Theory

1. A cell is the structural and functional unit of all living organisms.

2. All the living organisms are made up of cells.

3. Cells are formed from pre-existing cells.

Unicellular Organisms – The organisms that consist of a single cell such as Amoeba.

Multicellular Organisms – The organisms which contain various cells that perform different functions in the organism such as plants fungi and animals

How can multicellular organisms originate from a single cell?

A cell has the capability to divide itself into cells of its own type. Therefore, more cells can generate from an already existing cell.

The Shape of the Cell

The shape of the cell may vary depending upon the type of function they perform in an organism.

Cells are capable of changing their shape. For example, the white blood cells and amoeba can change shapes on their own.
