Answer

Brief Explanations:

The cell theory has three main parts: all living organisms are made of cells, the cell is the basic unit of life, and cells come from pre - existing cells. The other options are not part of the cell theory. Having a nucleus is not a requirement for all cells (prokaryotes lack a nucleus), seeing single - celled organisms with a microscope is a practical aspect not part of the theory, and some organisms are single - celled and can live.

Answer:

cells come from pre - existing cells
