These cone-producing plants belong to a fascinating group called gymnosperms, which have been around since the age of dinosaurs! Unlike flowering plants, gymnosperms have naked seeds, meaning their seeds aren't enclosed in a fruit. Think of majestic trees like pines and spruces—these beauties flourish in various ecosystems, showcasing the wonders of nature's diversity! Fungi play a vital role in our ecosystems, and bread mould, specifically Rhizopus, has a network of hyphae that creep along surfaces, forming a strong foundation to extract nutrients. These structures aren’t just for show; they allow bread mould to thrive, breaking down organic material, which is essential for nutrient cycling in ecosystems. So next time you see some mouldy bread, remember, it's nature working to recycle that food!
