Features of Fungi • mostly multicellular, absorptive heterotrophs • can be classified nutritionally as… – Saprobes • absorb nutrients from nonliving matter – Parasites • absorb nutrients from body fluid of a living host – Mutualists • examples include mycorrhizae and lichens Structure of Fungi • Mycelium—the fungal organism – consists of a mass of filaments called hyphae • Hyphae – arise by mitosis from a haploid spore – divided into cells by cross walls
