Angiosperm Lab Angiosperms are part of the group Magnoliophyta, which includes crops and most horticultural plants. Angiosperms differ basically from gynmosperms because they have an ovary covering their seeds, whereas gymnosperms do not. Fruits or flowers cover their seeds. Our economy depends on angiosperms more than any other plant group, and 80% of the known living plants on Earth are angiosperms. Fossils show that the earliest angiosperms existed during the Early Cretaceous Period (144 to 97.5 million years ago). Angiosperms have evolved over the years, developing specialized vascular tissues and extensive root systems. They evolved this way to survive living in a maily terrestrial environment. Angiosperms are a huge part of the plant world and our economy, and we should work to protect the bidiversity that exists within them.
