How are the organelles of a single cell act like the organs of a multicellular organism?

All of the organelles work together to carry out the functions of the cell as a whole, just as organs do to an organism. For example, mitochondria are the sites of cellular respiration; they provide energy to the cell. The nucleus is the "control center." Lysosomes digest and hydrolyze cellular wastes. In this way, each organelle plays a specific role in the functioning of the cell and is necessary for the cell to survive.

A single cell's organelles are similar to an organism's organs in that they each have specific roles that are required for the overall survival and functioning of the cell or organism. For example, just as organs cooperate to maintain homeostasis and carry out various physiological processes, so do organelles within a cell to carry out specific functions like energy production, protein synthesis, waste management, and cell communication. Each organelle has a distinct structure and function that contributes to the overall health and function of the cell, just as organs do within a multicellular organism.
