5 Must Know Facts For Your Next Test

1. Basidiomycota produce sexual spores known as basidiospores.
2. They are critical decomposers in ecosystems, breaking down complex organic materials.
3. The life cycle of Basidiomycota includes a prolonged dikaryotic stage where two nuclei coexist in each cell.
4. Many Basidiomycota form symbiotic relationships with plants through mycorrhizae, aiding in nutrient exchange.
5. Common representatives include edible mushrooms like Agaricus bisporus and pathogenic fungi such as Cryptococcus neoformans.
