If you recall, there are four natural extant groupings for plants: the Bryophytes, Pteridophytes, Gymnosperms and Angiosperms. In this laboratory, you will study seed plants: the Gymnosperms and the Angiosperms. Both seed plant groups are thought to have risen from a group of extinct phylum Progymnospermophyta.These progymnosperms had intermediate characteristics between ancestral ferns (an extinct seedless vascular group) and seed plants.f you recall, there are four natural extant groupings for plants: the Bryophytes, Pteridophytes, Gymnosperms and Angiosperms.
