DNA in eukaryotic cells is found inside the nucleus, while DNA in prokaryotic cells is located in the cytoplasm. Eukaryotic cells are generally larger and more complex than prokaryotic cells. Eukaryotic organisms include animals, plants, fungi, and paramecia. Prokaryotic organisms include bacteria and archaea. Let's learn more about them in this video.

The nucleus stores DNA. The endoplasmic reticulum and Golgi body are involved in protein maturation and transport. Mitochondria generate usable energy for the cell. Chloroplasts carry out photosynthesis. Vacuoles are storage compartments that sequester waste and help maintain water balance. Lysosomes contain enzymes that help break down waste.
