similarities between gymnosperms and higher cryptogams
The key difference between angiosperms and gymnosperms is how their seeds are developed. Both groups use pollen to facilitate fertilization, though angiosperms have an incredible diversity of pollination strategies that are not found among the gymnosperms. Our goal is to make science relevant and fun for everyone. Like the pteridophytes, many taxa are now extinct, relics of a much larger group. Leaves decurrent and the twigs with roughened by peg-like projections that persist after leaves fall.

Angiosperms typically drop their leaves when the seasons change and chlorophyll production ceases. In 1883 a German botanist A.W Eichler divided the whole plant kingdom intoPhanerogamsand Cryptogams. Four major groups within the gymnosperms are usually recognized - these sometimes each considered its own phylum (Cycadophyta, Ginkgophyta, Gnetophyta, Pinophyta).
