all living organisms must be unicellular
all living organisms must have a nucleus
clear all

Explanation:

The cell - theory states that all living organisms are made up of cells. Some living organisms are unicellular (composed of one cell) and some are multicellular (composed of many cells). Prokaryotic cells do not have a nucleus while eukaryotic cells do. Since the samples are from living organisms and non - living objects, the fundamental characteristic that defines living organisms among the options is that they are made up of cells. Living organisms are not just molecules (they are complex structures made of molecules organized into cells). Not all living organisms are unicellular, and not all have a nucleus (prokaryotes lack a nucleus).

Answer:

All living organisms are made up of cells
