Explanation:

Cell theory has three fundamental parts: all living things are made of cells, cells are the basic unit of life, and cells come from pre - existing cells. For the size - order question, the correct hierarchy from largest to smallest is organism, organ system, organ, tissue, cell, organelle. Prokaryotic and eukaryotic cells are first distinguished at the organelle level as eukaryotic cells have membrane - bound organelles while prokaryotic cells do not.
