Stem of gymnosperm is aerial.
Stem of pteridophytes are mostly underground.
Tree Ferns have long aerial stems but these are Pteridophytes. The real difference is that gymnosperms bear seeds pteridophytes are without seeds.
Gymnosperms are a group of seed bearing plants including conifers, there are only between 700 and 900 species. Pteridophytes produce neither seeds nor flowers, they reproduce by spores. They are often planted as ornamentals.
gymnosperms
No, tracheophytes and pteridophytes are not the same thing. Tracheophytes refer to vascular plants that have specialized tissues for water and nutrient transport, including both seed-producing plants (gymnosperms and angiosperms) and non-seed plants (ferns, horsetails, and lycophytes). Pteridophytes specifically refer to non-seed vascular plants that reproduce via spores, such as ferns, horsetails, and lycophytes.
Botanical snakes is not a scientifically recognized term. It might refer to plants that have snake-like characteristics in their appearance, such as twisted or winding stems or leaves.
Actually Pteridophytes are ferns and the like. They have spores. I think Gymnosperms is the term you're thinking of. It comes from the Greek for naked seed.

gymnosperms
Pteridophytes have naked seeds called 'Spores'. It is a Cryptogammae as reproductive organs are not visible at all. Phanerogams have seeds which store food. Reproductive organs are visible. (Flowering Parts or Cones)

In angiosperm seeds are enclosed inside the ovary whereas in gymnosperm seeds are naked (i. e. born on megasporophyll) Gymnosperms have archegonium for egg whereas in angiosperms it is replaced by an embryo sac.

The difference between gymnosperms and angiosperms is that gymnosperms develop cones as their seed to use in the fertilization process, and angiosperms produce flowers and fruits as their seed to use in the fertilization process.
The major groups of Plantae are bryophytes (mosses, liverworts, and hornworts), pteridophytes (ferns and horsetails), gymnosperms (conifers, cycads, ginkgoes), and angiosperms (flowering plants). Each group has unique characteristics and reproductive strategies.
Plants belonging to bryophytes and Pteridophytes etc. reproduce with spores and thoseof gymnosperms and angiosperms reproduce with seeds.
There are various types of submerged plants, they may be algae , brophytes ,pteridophytes, gymnosperms and angiosperms. Submerged plants also reproduce like terrestrial ones. There may be isogamy , anisogamy, oogamy.
