vlada-n [284]

Gymnosperms lack fruits so angiosperms are more advanced than them.

Compared to gymnosperms, flowering plants may thrive in a wider range of settings. Compared to gymnosperms, flowering plants mature more quickly and generate more seeds. Additionally, angiosperms have more complex and specialized woody tissues. Gymnosperms lack flowers and fruits and have unenclosed or coverless seeds on the surface of scales or leaves, in contrast to angiosperms, generally known as flowering plants, which have seeds that are contained within an ovary (typically a fruit).
