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. video https://cdn.kastatic.org/googleusercontent/JzsKsXQI3JwamHPrup3tPIx1LvFuypJN7IarCsriPalsYSLciMIksgGndNkGHQ8UabCK8NZWSuh6iOMy5ku2oA4s Prokaryotic and eukaryotic cells Eukaryotic cells contain membrane-bound organelles (such as the nucleus and mitochondria), while prokaryotic cells do not.

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.

For example, mitochondria help release energy that the cell can use for other tasks, and the nucleus contains the genetic information. The cell membrane forms the boundary that controls what enters and leaves the cell. In plant cells, chloroplasts enable photosynthesis and the cell wall provides structure.
