What is the fundamental unit of life?

Cells
Molecules
Enzymes
DNA

The correct answer is: Cells

Cells are the fundamental unit of life because they are the smallest functional and structural unit of all living organisms. Molecules and enzymes are not considered the fundamental unit of life because they do not exhibit all of the characteristics of living things, such as growth, reproduction, and response to stimuli. DNA, while vital for life, is not a unit of life on its own and requires the functioning of cells in order to carry out its functions. Therefore, cells are the most important and fundamental unit of life.
