Explanation:

1. All cells have a cell - membrane that controls what enters and leaves the cell. They also contain genetic material (DNA or RNA) for inheritance and protein - synthesis instructions.
2. The main ideas of the cell theory are: all living organisms are made of cells; cells are the basic unit of life; and all cells come from pre - existing cells.
3. Prokaryotes lack a nucleus and membrane - bound organelles, while eukaryotes have a nucleus and various organelles. Both have a cell membrane, genetic material, and ribosomes for protein synthesis.

Answer:

1. They have a cell - membrane and genetic material.
2. All living organisms are made of cells; cells are the basic unit of life; all cells come from pre - existing cells.
3. Difference: Prokaryotes lack a nucleus and membrane - bound organelles. Similarity: Both have a cell membrane, genetic material, and ribosomes.
