Question

Is a conifer a seedless vascular plant?

Answer 1

It's a gymnosperm

Explanation:

Seedless vascular plants tends to be like ferns. Unlike mosses (bryophytes) they do have vascular tissue, which is why they have long leaves, or fronds though psilotum (whisk ferns) and equistem (horse tails) don't look like traditional ferns.

Conifers are gymnosperms. The are not seedless, they have cones. They have male cones and female cones and the male cones which interact, when the male fertilizes the female cone and forms an embryo that becomes a saprophyte (tree). They are gymnosperms with cork cambium, bark and wood. Picture a Christmas tree.
