- Golgi Body (or Golgi apparatus) modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles. It also plays a role in the synthesis of some polysaccharides and is involved in the formation of lysosomes. - Smooth Endoplasmic Reticulum (SER) is involved in the synthesis of lipids (including steroids), detoxification of drugs and poisons, and storage of calcium ions. - Ribosomes are the sites where protein synthesis occurs. They can be free in the cytoplasm or attached to the rough endoplasmic reticulum. - Lysosomes are membrane-bound organelles containing hydrolytic enzymes that digest waste materials and cellular debris. They are often referred to as the "suicide bags" of the cell due to their role in autolysis.
