Prokaryotic and Eukaryotic cells

What is a Prokaryotic Cell? Prokaryotic cells are cells that do not have a true nucleus; the DNA in prokaryotic cells is not completely separated from the rest of the cell by a nuclear membrane (envelope) and is not arranged in strands called chromosomes. Prokaryotic cells do not have membrane bound organelles. Prokaryotic cells are bacteria

What is a Eukaryotic Cell? Eukaryotic cells have the DNA is organized into structures called chromosomes and the chromosomes are separated from the cytoplasm by a nuclear membrane. Eukaryotic cells have membrane bound organelles. Eukaryotic cells are animal, plant, fungi, and protist.

Prokaryotic cells differ from eukaryotic cells in other ways: Prokaryotic cells lack most of the other organelles which are present in the cytoplasm of eukaryotic cells. Prokaryotic cells do not contain mitochondria but they can obtain energy from either sunlight or from chemicals in their environment. Prokaryotic cells, however, do contain ribosomes, the site of protein synthesis. Most prokaryotes are unicellular organisms, such as bacteria.
