All cells are not the same because not all cells contain membrane-bound organelles. 
Prokaryotic cells lack membrane-bound organelles. In contrast, eukaryotic cells contain membrane-bound organelles like an endoplasmic reticulum, lysosomes, and importantly, a nucleus.
The nucleus is where genetic information (DNA) is stored. However, it is only present in eukaryotic cells. Prokaryotic cells do not possess a nucleus, the DNA is found in the cytoplasm.
