Basic physiological differences such as reproductive organs, and structure.


Both have vascular tissue of a sort, but gymnosperms are heterosporus. Not all ferns have both types of spore. The reproductive parts of gymnosperms are in cones, where ferns have sperm and sorii (grainy dots that are the indusium) on the underside of their leaves. Gymnosperms require wind to pollinate but ferns need water for the sperm to swim through. Gymnosperms have wood lignin and cork cambium, are more structurally rigid and thick because of layers of dead secondary vascular tissue. Ferns do not have wood or bark.
