Explain the differences between prokaryotes, eukaryotes and mitochondria (eukaryotic organelle). Which 2 of those 3 are most similar?

Eukaryotic

Cells with a differentiated nucleus that contains all the DNA, limited by nucleus membrane, and has a cytoplasm limited with the plasma membrane that contains organelles.

The ribosomes are bigger, 80 S (svedbeg is the measuring unit)

Procaryotic

All its genetic material spread on the cytoplasm.

This kind of cell does not have organelles. All biologic processes made in specific places in the plasma membrane.

The ribosomes are smaller, 70 S.

Mitochondria

It's an organelle you can find inside a eukaryotic cell.

It has two membranes, one outsider, and one insider.

The insider one has folded.

Scientific believe that millions of years ago, the mitochondria was a bacteria and the eukaryotic cell phagocyte it and became part of it.

The ribosomes are the same size that procaryotic cells.
