Prokaryotic and eukaryotic cells are two types of cells that differ in their complexity and structure. Prokaryotic cells are simpler and smaller in structure, while eukaryotic cells are complex and larger in size. Prokaryotic cells, such as bacteria, lack a nucleus and membrane-bound organelles, whereas eukaryotic cells, such as animal and plant cells, have a nucleus and organelles surrounded by membranes. Prokaryotic cells are also haploid, meaning they contain only one set of chromosomes, while eukaryotic cells are diploid, meaning they contain two sets of chromosomes. Prokaryotic cells reproduce asexually, while eukaryotic cells reproduce sexually or asexually. Finally, prokaryotic cells typically have a cell wall composed of peptidoglycan, while eukaryotic cells have a cell wall composed of cellulose.
