Many vascular plants do not have flowers. Ferns are an example. I think all flowering plants are vascular, but if any are not, they evolved from vascular plants. I know that some species of duckweed have no roots or stems, and though I can imagine evolution of a flower that is entirely without conductive tissue when it is floating on water and as small as some duckweed flowers, I doubt it ever happened.

Gymnosperms have cones and angiosperms have flowers/fruits
No, angiosperm seeds are not protected by cones. Angiosperms produce seeds enclosed within a fruit, which develops from the ovary of a flower. Conifers, which are gymnosperms, produce seeds that are typically protected by cones.

By cones. You should do your own research instead of coming to answers.com. Thank you. Have a great day.

no, an oak tree is an angiosperm. some examples of gymnosperms are pine trees or brigham trees.
No, conifers and angiosperms are not the same. Conifers are a group of plants that produce seeds in cones, while angiosperms are flowering plants that produce seeds within a fruit. Angiosperms are a larger, more diverse group that includes both trees and non-woody plants, while conifers are a specific type of woody plant.
