In what ways does pollination in gymnosperms differ from pollination in angiosperms?

One main difference is that gymnosperms typically rely on wind for pollination, while angiOSperms often rely on animals like bees for pollination. Additionally, gymnosperms have exposed seeds, while angiOSperms have seeds enclosed within a fruit. Finally, gymnosperms do not produce flowers, while angiOSperms do.
