Which statement is one of the three parts of cell theory? The smallest living things are single cells, and cells are the functional units of multicellular organisms. There are three types of cells, prokaryotic, eukaryotic plant, and eukaryotic animal. Cells make up tissues, tissues make up organs, organs make up systems, systems make up organisms. Cell organelles can be membrane-bound or not membrane-bound.

Based on the information provided within the question, from the answers provided the only statement that is one or the three parts of cell theory is that the smallest living things are single cells, and cells are the functional units of multi-cellular organisms. Which although phrased differently it is explaining that all living things are made up of cells, from the smallest one celled organisms to multi-cellular organisms like us.

The other two parts of cell theory are that all living cells come from pre-existing cells by a process called cell division and that the cell is the fundamental unit of structure and function in all living organisms. Which the other answers provided do not match.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Answer:

The smallest living things are single cells, and cells are the functional units of multicellular organisms.

Explanation:

Cellular theory is formed by ideas from Schleiden, Schwann and Virchow. The first two proposed the basis of this theory. Cellular theory can be divided into three postulates:

All living things are made up of cells and their derived structures. The smallest living things are single cells. Thus, cells are the morphological units of living beings;

In the cell are processes that are fundamental to life. This means, then, that cells are the functional or physiological units of living beings;

All cells only originate from other pre-existing cells. With this postulate, it is considered that cells perform cell division.
