What does the function of a pine cone on a evergreen tree make?

Answer 1

I think you're a little confused. Pine cones come from pine trees. Evergreens are any plant that doesn't lose its leaves ever year. Not all evergreens are needle leaf trees. Not all needle leaf plants are evergreen. Not all evergreens have cones. And not all plants with cones are pines.

But... to answer your question... A cone on a plant (be it a pine, spruce, fir, yew, cedar, redcedar, redwood, larch, or hemlock) is a reproductive organ. Most conifers have separate male and female cones. The male cone has spores that contain sperm. The spores are dispersed by air and land on the female cone (usually of another plant.) After the female cone is fertilized, seeds form.
