Gymnosperms - 'naked seed'. But that does not include mosses, which are plants, but do not have true seeds. Ferns are vascular plants, but don't have seeds either.
Conifers are non-flowering plants.
This is already its scientific name. There is no other name for it accept for the definition.
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).
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.
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).
It is a flowering plant
There's no mystery here. Non-flowering plants don't have flowers.
it is about the plants that always flowers
