Which magnoliophyta groups are NOT pollinated by bees and why?

Answer 1

Well, this can, in part, be answered by thinking about why bees/wasps are generally attracted to some flowers as well as the different types of flower structure combinations commonly found in Angiosperms. I'd say that bees and wasps are generally attracted to flowers that have petals/sepals so if we think about which plants don't have petals or sepals, that could be a key part of the answer. So, plants that have small, inconspicuous flowers like willows, oaks, hickories, grasses, rushes, and sedges most likely won't be pollinated by bees as they mostly rely on wind for pollen dispersal.

This is only part of the answer as there are other more conspicuous flowers that bees typically don't prefer, however, that answer could get fairly complicated quickly, so if you want to know more, feel free to send me a message!
