2. Life cycle:
• asexual reproduction: Zygomycota fungi primarily reproduce asexually through the production of sporangiospores. Sporangia develop at the tips of specialized hyphae called sporangiophores and release numerous sporangiospores into the environment. These spores can disperse, germinate, and give rise to new hyphae.
• sexual reproduction: Zygomycota fungi undergo sexual reproduction involving the formation of zygosporangia. This process typically occurs when two compatible strains (mating types) come into contact and their specialized hyphae fuse. The fusion results in the formation of a zygosporangium, within which the nuclei from both strains combine to form thick-walled zygospores. These zygospores can remain dormant until favorable conditions trigger germination and the production of new hyphae.
• germination and growth: upon germination, both asexual sporangiospores and zygospores can give rise to new hyphae. These hyphae can grow and branch, forming a mycelium that spreads and explores the surrounding environment for nutrients.
• environmental adaptations: Zygomycota fungi can exhibit adaptations to various environmental conditions. Some species are capable of rapid growth and can colonize organic substrates efficiently, such as bread or decaying plant material. Others, like certain species of mucor, can tolerate extreme environments, including high temperatures or high sugar concentrations.
