What trait of both daisies and oak trees puts them in the same group?

Both daisies and oak trees are classified as angiOSperms, meaning they are flowering plants that produce seeds enclosed within a fruit. This shared trait of flowering and seed production distinguishes them from other plant groups, such as gymnosperms, which do not produce flowers. Additionally, both exhibit a life cycle that includes the formation of seeds, contributing to their reproductive success in various environments.
