What are the pteridophytes & spermatophytes?
Vascular plants are subdivided into two major categories, pteridophytes, and spermatophytes. Pteridophytes (Greek for “fern plant”) include ferns and horsetails that reproduce asexually by spores. Spermatophytes (Greek for “seed plant”) include conifers and flowering plants that reproduce sexually by seed.
What are bryophytes pteridophytes and gymnosperms?
Bryophytes are the most preliminary type of plants which includes mosses and liverworts. Pteridophytes. Pteridophytes include fern plants. Gymnosperms. Gymnosperms are seed-bearing plants and include cycads and conifers.
What are bryophytes and pteridophytes?
Bryophytes are non-vascular plants, without xylem and phloem. They reproduce by gamete formation. For eg., mosses, liverworts and hornworts. On the contrary, pteridophytes are vascular plants with xylem and phloem.
What is spermatophytes in biology?
Spermatophyte. (Science: botany) division of the plant kingdom, consisting of plants that reproduce by means of seeds.
What are the difference between spermatophytes and bryophytes?
Spermatophytes are non-thalloid plants (i.e. plant body is distinguished into roots, leaves and stems) while bryophytes are thalloid plants (i.e. plant body is not distinguished into roots, stem and leaves). Spermatophytes are vascular plants while bryophytes are non-vascular plants.

What is the main difference between pteridophytes and bryophytes?
Bryophytes consist of a leafy or thalloid plant body. Pteridophytes consist of roots, stems, and leaves. Vascular tissue is absent.
What is the difference between bryophyta and bryophytes?
Bryophyta vs. bryophytes: Bryophyta refers to the moss division, and bryophytes refers to the broader group which includes the division Bryophyta, liverworts, and hornworts.
What do you mean by bryophytes?
bryophyte, traditional name for any nonvascular seedless plant—namely, any of the mosses (division Bryophyta), hornworts (division Anthocerotophyta), and liverworts (division Marchantiophyta). Most bryophytes lack complex tissue organization, yet they show considerable diversity in form and ecology.
What are the characteristics of spermatophytes?
General characteristics
- The plant has roots, stems, leaves and seed bearing structures.
- They produce seeds.
- They have chlorophyll hence photosynthetic.
- They have vascular tissue is highly developed with xylem tissue consisting of both xylem tissue and tracheids.
Are bryophytes spermatophytes?
is that spermatophyte is (botany) any plant that bears seeds rather than spores while bryophyte is (botany) any plant of the division bryophyta, defined sensu lato to comprise the mosses, liverworts and hornworts and corresponding to all embryophytes that are not vascular plants.
Which plants are spermatophytes?
The spermatophytes (seed plants), which include gymnosperms and angiosperms, are some of the most important organisms on Earth. Angiosperms are the most diverse and widely studied seed plants.
