All flowering plants flower to attract pollinators to help to produce either fruit or seeds, so your question is difficult to give an answer to. If you can be a bit more specific I'll try to help.
Flowering plants require pollinatio non-flowering plants do not.
You get both flowering plants and non-flowering plants; non-flowering are things like mosses, ferns and liverworts which produce spore, flowering plants produce seeds
flowering plants and non-flowering plants
Plants are classified as flowering(angiosperms) or non flowering(gymnosperms).
Conifers are non-flowering plants.
Non-flowering plants are separated from flowering plants at the division level in the taxonomic scheme. Non-flowering plants belong to the divisions like Bryophyta (mosses), Hepatophyta (liverworts), and Pteridophyta (ferns), while flowering plants belong to the division Magnoliophyta (angiosperms).
