In the nucleus mRNA goes from the nucleus to the ribosomes. The nucleus and the ribosomes work together to perform protein synthesis. In plant cells the mitochondria and the cytoplasm work together to provide energy for the cell. Golgi structures and packages proteins, and the ribosomes do protein synthesis. The vacuoles also help the golgi apparatus because they store the proteins. The lysosomes helps all the cells because it breaks down lipids, carbs and proteins so that it can work throughout the rest of the cell. These organelles are all working together.
