1. Nucleolus: Nucleolus takes part in the production of subunits of the ribosome that unites to form ribosomes. Hence, the nucleolus plays an important role in the synthesis of proteins and in the production of ribosomes in eukaryotic cells.
2. Endoplasmic reticulum (ER): The endoplasmic reticulum is a tubular network of membranes found within the cytoplasm of the eukaryotic cell.
ER is responsible for the production and secretion of steroid hormones, and the synthesis of essential lipids such as phospholipids and cholesterol. It is also responsible for the metabolism of carbohydrates. ER releases calcium ions, which are necessary for the nervous system and muscular system.
3. Golgi bodies: The main function of Golgi bodies is the packaging and secretion of proteins. It receives proteins from Endoplasmic Reticulum. It packages it into membrane-bound vesicles, which are then transported to various destinations, such as lysosomes, plasma membrane, or secretion. They also take part in the transport of lipids and the formation of lysosomes
4. Ribosomes: Ribosomes synthesize proteins in the cell. Hence are called protein factories of the cell.
5. Lysomsomes: The key function of lysosomes is digestion and removal of waste.
When a cell is old or injured this rapidly destroys organelles hence called suicide bags.
