New to the Glossary: Angiosperm, Bryophyte, Gymnosperm, Lycophyte, Pteridophyte, Spermatophyte
Land plants have evolved from ten major living lineages, with like plants being grouped together based on whether or not they have vascular tissue and whether or not they have seeds. The two groups of vascular seed plants are the angiosperms (meaning “vessel seeds”) and the gymnosperms (meaning “naked seeds”).
