Fungi are eukaryotic organisms made up of masses of hyphae called mycelium. Fungi exists in different forms ranging from parasitic ones that cause harm to other organisms to the mutualistic ones whose activities benefits other organisms. According to the question, a good example of a mutualistic fungi is the one that forms mycorrhizae with plants.
