Sporopollenin can be a chemically resistant polymer present in the outer cell partitions of spores and pollen of land plants to blame for the survival of early land plant spores and the pollen of seed plants within the fossil history. It really is commonly regarded as a marker for the beginning of land plant evolution during the Ordovician interval.[88]
[76] Other people make specialised products like the cellulose and lignin made use of to build their bodies, and secondary goods like resins and aroma compounds.

Nonvascular land plants are embryophytes that deficiency the vascular tissues xylem and phloem. They include things like mosses, liverworts and hornworts. Pteridophytic vascular plants with legitimate xylem and phloem that reproduced by spores germinating into absolutely free-dwelling gametophytes developed in the course of the Silurian interval and diversified into quite a few lineages in the late Silurian and early Devonian. Reps of the lycopods have survived to your existing working day. By the end of your Devonian time period, quite a few teams, including the lycopods, sphenophylls and progymnosperms, experienced independently progressed "megaspory" – their spores had been of two distinct dimensions, greater megaspores and more compact microspores. Their decreased gametophytes made from megaspores retained within the spore-creating organs (megasporangia) of your sporophyte, a affliction generally known as endospory.
