Zygomycetes are a class of fungi known for their unique reproductive structures called zygosporangia. These fungi typically thrive in soil and decaying organic matter, playing a crucial role in nutrient cycling. They reproduce both sexually and asexually, with asexual reproduction often occurring through the production of spores. Common examples of Zygomycetes include molds like Rhizopus stolonifer, which is often found on bread. These fungi are characterized by their filamentous structure, known as hyphae, which can spread rapidly in suitable environments. Zygomycetes are important in various ecological processes and have applications in food production and biotechnology.
