Biology question Help. How do the following organelles work together to keep a cell alive?

The mitochondria provides all the energy for the cell.  The nucleus is the brain of the cell and holds all the DNA.  The ribosomes are part of the process that create new proteins.  Chloroplast use smaller organelles inside of them to help in photosynthesis in plant cells.  The cytoplasm is a network of tubes of various sizes that help give the cell its shape and allows for easy movement within the cell (acts as the highway).  Cell wall are only found in plant cells and give the cell a rigid shape.  Cell membranes are in both plant and animal cells and provide some protection but mainly serve as a way in and out of the cell.  The rough endoplasmic reticulum is the main area for the synthesis of proteins and the smooth endoplasmic reticulum is the membrane factory for the cell.  The golgi apparatus helps with packaging proteins and sends them to different parts of the cell or even outside of the cell.  The lysosome helps with the breakdown of dead organelles.  Vacuoles are mainly in plant cells but can be found in animal cells and store water and food.  Cilia are small hair-like structures on the outside of most protists that help with locomotion.  Flagella is one longer structure that also helps with locomotion.
