22. 1 what are the key features of fungi: fungal bodies consist of slender threads. Cells are surrounded by cell walls composed of chitin, a structural polysaccharide. The filamentous body of a fungus: fungi obtain their nutrients from other organisms. Secrete enzymes outside their bodies and absorb the digested nutrients. Fungal decomposers feed on dead organic material and wastes. Fungal parasites absorb nutrients from cells of living hosts and may cause disease. Some symbiotic fungi live in mutually beneficial relationships with other organisms. Fungi reproduce by spores: spores are tiny reproductive packages capable of developing into adult fungi. They are often produced in large numbers, and are spread by animals or air currents: most fungi can reproduce both asexually and sexually. Asexual reproduction: mycelium produces asexual spores that develop into mature fungi, this results in the rapid production of genetically identical clones, sexual reproduction is what makes variation, asexual reproduction only produces offspring that are identical, sexual reproduction:
