Pteridophytes vs Gymnosperms
(Similarities and Differences between Pteridophytes and Gymnosperms)
Pteridophytes are a group of primitive land plants belongs to Cryptogams. They are the first plant group with vascular tissue for the conduction of water and food materials and hence they are called as Vascular Cryptogams.
Gymnosperms are a group of primitive seed-producing plants of Spermatophytes (Phanerogams). They are ‘Naked-Seed’ Plants characterized by naked ovules (i.e., ovule without the ovary). The ovules of Gymnosperms are borne directly on the surface of the megasporophyl. Since ovary is absent, Gymnosperms do not produce fruits.
Pteridophytes occupy the intermediate position between Bryophytes and Gymnosperms (seed plants). Gymnosperms were believed to be originated from the Pteridophytes in the Devonian period (419 to 359 million years ago) of Paleozoic Era. Pteridophytes and Gymnosperms share many characteristics. In the previous posts, we discussed the General Characters of Bryophytes Pteridophytes and Gymnosperms. In this post, we will discuss the Similarities and Differences between Pteridophytes and Gymnosperms with Comparison Table.
