German botanist, Matthias Jacob Schleiden in 1838, observed different parts of the plants under the microscope and found that all of them are made up of cells. German zoologist, Theodor Schwann in 1839, observed parts of the animal body and noticed that cells had an outer layer which is also called as plasma membrane. Schleiden and Schwann together gave cell theory. This theory slates that bodies of all living organisms are made up of cells and their products. Rudolf Virchow studied that all cells arise from the pre-existing cells. In other words, the existing cells divide to form new cells. He stated this in Latin as “omnis cellula-e-cellula” and on this basis proposed the modern cell theory.

Understanding Cell Theory
Cell theory is a fundamental concept in biology that outlines the properties and functions of cells, which are the basic units of life. The theory states that:
- All living organisms are composed of one or more cells.
- The cell is the basic unit of life.
- All cells arise from pre-existing cells.
Exceptions to Cell Theory
While cell theory is widely accepted, there are exceptions, and one notable exception is viruses.
Why Viruses Are an Exception
- Non-cellular Structure: Viruses do not have a cellular structure. They consist of genetic material (DNA or RNA) surrounded by a protein coat, but they lack the cellular machinery necessary for metabolism and reproduction.
- Dependency on Host Cells: Viruses cannot reproduce independently; they require a host cell to replicate. Upon invading a host, they hijack the host's cellular machinery to produce more virus particles.
- Lack of Metabolism: Viruses do not carry out metabolic processes on their own, which is a characteristic feature of living cells.
Other Exceptions
- Bacteria: These are unicellular organisms and fit within the cell theory.
- Fungi: These are multicellular and also adhere to the principles of cell theory.
- Lichens: Composed of fungi and algae or cyanobacteria, they are complex life forms but still consist of cells.
Conclusion
In conclusion, while most living organisms are made up of cells, viruses stand out as a significant exception due to their unique characteristics that challenge the traditional cell theory. Understanding these exceptions is crucial for studying microbial life and the nature of viruses in the field of biology.
