What is the basic unit of living organisms?

Cell
Nucleus
Molecule
Proteins

The correct answer is: Cell

Living organisms consist of one or more cells, which are the basic units of life. While nucleuses, molecules, and proteins are all important components of living organisms, they are made up of cells and not considered the most essential or basic unit. Without cells, these components would not be able to function within an organism.
