Keisya Prokaryotes, unlike eukaryotes, lack several membrane-bound organelles, including the endoplasmic reticulum. The endoplasmic reticulum is a complex network of membranes that is involved in a variety of cellular functions, including protein synthesis, lipid metabolism, and detoxification. Prokaryotes do have ribosomes, which are small organelles that are responsible for protein synthesis. However, ribosomes in prokaryotes are … Read more
