Describe key structural differences between prokaryotic and eukaryotic cells.

Eukaryotic cells are larger and more complex than prokaryotic cells. The eukaryotic cell contains a nucleus, which contains genetic material in the form of linear chromosomes. However, prokaryotic cells contain no nuclei; instead, their genetic material is contained within circular pieces of DNA. The prokaryotic cell contains a cell wall, which is made up of glycoprotein. Some, but not all, eukaryotic cells contain cell walls- for example, plant cells. Unlike prokaryotic cells, eukaryotic cells also contain membrane-bound organelles. These include mitochondria, a golgi apparaus, an endoplasmic reticulum, and ribosomes. Plant cells also contain chloroplasts.
