Introduction
The cell is considered as the fundamental unit of life because it is the smallest structural and functional unit of life.

Structural organization of living organisms
All living organisms have a cellular organization that ranges from unicellular organisms to multicellular organisms.

The cell theory
The cell theory states that all living organisms are composed of one or more cells, and that the cell is the basic unit of life.

Functional organization of living organisms
The cell is responsible for various functions in living organisms such as metabolism, growth, and reproduction.

Cell types
There are two main types of cells - prokaryotic and eukaryotic cells. Prokaryotic cells are simple in structure and lack a well-defined nucleus, while eukaryotic cells are complex in structure and have a well-defined nucleus.

Cell structure
A typical eukaryotic cell has various organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and cytoskeleton.

Significance of cell
The cell is considered as the fundamental unit of life because it is the basic building block of all living organisms. It carries out various functions that are essential for the survival of living organisms.

Conclusion
In conclusion, the cell is considered as the fundamental unit of life because it is the smallest structural and functional unit of life. It is responsible for carrying out various functions that are essential for the survival of living organisms.

Cell is considered as the fundamental unit of life as all the functions take place at cell level
