Out of the following given choices;
They are all made of eukaryotic cells.
They are all made of prokaryotic cells.
They are all organisms made of cells.
They all reproduce in the same way.
The answer is They are all organisms made of cells. The cell is the basic unit of a living organism. A cell is a structure that is bound by a membrane and contains organelles and DNA (that contains coded instruction on how the cell should behave). While a bacterium has one cell that functions on its own, a rose and an elephant are higher organisms with numerous cells that function together.
