Answer:

Eukaryotic cells have a nucleus surrounded by a nuclear envelope that consists of two lipid membranes, according to Nature Education. The nucleus holds the eukaryotic cell's DNA. Prokaryotic cells do not have a nucleus; rather, they have a membraneless nucleoid region (open part of the cell) that holds free-floating DNA, according to Washington University.

The entire DNA in a cell can be found in individual pieces known as chromosomes. Eukaryotic cells have many chromosomes which undergo meiosis and mitosis during cell division, while most prokaryotic cells consist of just one circular chromosome. However, recent studies have shown that some prokaryotes have as many as four linear or circular chromosomes, according to Nature Education. For example, Vibrio cholerae, the bacterium that causes cholera, has two circular chromosomes.

Organelles in Eukaryotic Cells: Eukaryotic cells have several other membrane-bound organelles not found in prokaryotic cells. These include the mitochondria (convert food energy into adenosine triphosphate, or ATP, to power biochemical reactions); rough and smooth endoplasmic reticulum (an interconnected network of membrane-enclosed tubules that transport synthesized proteins); golgi complex (sorts and packages proteins for secretion); and in the case of plant cells, chloroplasts (conduct photosynthesis). All of these organelles are located in the eukaryotic cell's cytoplasm.

The main differences between prokaryotic and eukaryotic cells are the presence of a nucleus, the size and complexity of the ribosomes, how the cells reproduce and the presence of a cell wall.
