Analyze the current scientific observations which are the basis of discovery of ideas of cell theories?

Cell theory has 3 main postulates:

• All living things are composed of cells (one or more).


• Cell is the basic functional unit of life.


• All cells come from pre-existing cells.

Microscope has made the biggest contribution in development of the cell theory. Earlier it was impossible to see the cell, till Robert Hooke made a primitive microscope in 1655 to observe cells on a cork. Later, other scientists used microscopes to see cells in other structures (animals, plants, etc.) and biologists discovered cell organelle. 

In modern times, advances in biotechnology, especially the genetic methods have helped us confirm the ideas of cell theory. We can now confirm that cell is the smallest living unit and is capable of carrying out all the functions. We know now the basis of generation of cells from existing cells, we can also create synthetic cells and carry out changes in cellular structures. 

Hope this helps.
