A typical fungus has a nucleus—sometimes more than one per cell—that holds its genetic material (chromosomes). Other organelles that help a fungus cell to function include the cytoplasm (for movement of materials through the hydrae), mitochondria (converts energy), rough and smooth endoplasmic reticulum (makes the more complex proteins), and Golgi apparatus (forms many types of proteins and enzymes). Fungi also have, like bacteria, ribosomes, but those in bacteria are smaller and have a different way of reproducing.
