Angiosperms VS. Gymnosperms (physiological differences)
what are some of them, in terms of leaf structure, vascular tissues, etc? Looking at some of the agathis and podocarpus species, they look so much more like angiosperms, like flowering trees, than gymnosperms. So, I wonder, what are some other differences between angiosperms and gymnosperms besides the obvious seed structure? How about leaf structure, vascular differences, etc. Anybody know?
