Structural features of fungi Complete the following paragraph to describe the structural features of fungi. Solution The thallus of most fungi is known as a(n) mycelium. which is divided into a network of filaments called hyphae These hyphae increase the surface area, maximizing the absorption of nutrients. Some species of fungi have hyphae that are partitioned by walls of tissue called septae Fungal cells have cell walls comprised of chitin Similar to animals they store energy in the form of glycogen Fungi tend to be Nonmotile, although some do contain flagella at some point in their life cycle. Fungi reproduce sexually and asexually during their life cycles. Cells produced during the Asexual phase are called spores. These are haploid as they contain only one set of chromosomes.
