What is the Fundamental Structural and Functional Unit of Life

Question

What is the fundamental structural and functional unit of life?
A)atom
B)macromolecule
C)DNA
D)cell
E)organism

Accepted Answer

The cell is the fundamental structural and functional unit of life. All organisms are made up of cells, which carry out all of the basic functions necessary for life, such as metabolism, growth, and reproduction. Although atoms and macromolecules are important components of cells, they do not have the same level of complexity or autonomy as cells do. DNA is also important, but it is a molecule that is contained within cells and does not function on its own. Organisms are made up of cells, but they are not the smallest unit of life.
