Characteristics
• Once classified as Plant Kingdom due to cell wall
• Cell walls containing chitin (same material used to make the exoskeleton of insects)
• Heterotrophic: need to eat to obtain energy
• Structure has been adapted for two main functions: absorption of nutrients and reproduction
• The majority of a fungus is in the form of a mycelium (branching structure) typically found underground
• The reproductive structure (fruiting body) is the visible part of the fungus (above ground)
Structure of a Fungus
•Often the only visible parts of a fungus
are its reproductive structures
