What is pteridophyta and Spermatophyta?

The main difference between these two classes is that: Pteridophytes are vascular plants but they do not produce flowers and seeds which mean their source of reproduction is unknown or hidden. Examples are ferns, horsetails and lycophytes. On the contrary, Spermatophytes as the name indicates, are seed bearing plants.

What is pteridophyta and Spermatophyta?

The main difference between these two classes is that: Pteridophytes are vascular plants but they do not produce flowers and seeds which mean their source of reproduction is unknown or hidden. Examples are ferns, horsetails and lycophytes. On the contrary, Spermatophytes as the name indicates, are seed bearing plants.

What are the two types of Spermatophyta?

It includes two classes namely Gymnospermae and angiospermae.

What is phylum Spermatophyta?

Vascular plantSeed plants / PhylumVascular plants, also called tracheophytes or collectively Tracheophyta, form a large group of land plants that have lignified tissues for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue to conduct products of photosynthesis. Wikipedia

What classification is Spermatophyta?

Spermatophyte

What is the main difference between Pteridophyta and Spermatophyta?

Bryophyta has gametophyte predominance while Pteridophyta and Spermatophyta both have sporophyte predominance (and the main difference between Pteridophyta and Spermatophyta is that Spermatophyta has seeds). Bryophyta has approximately 20,000 species.

What are the similarities between Spermatophyta and Pteridophyta?

Both of them are free-living, the sporophytic generation being the maximum of their life cycle. Both of them have xylem and phloem tissues as their conducting tissues. Both of their bodies are differentiated into stem leaves and roots.

What are characteristics of Spermatophyta?

General characteristics of phylum spermatophyta

• The plant has roots, stems, leaves and seed bearing structures.
• They produce seeds.
• They have chlorophyll hence are photosynthetic.
• They have vascular tissue is highly developed with xylem tissue consisting of both xylem tissue and tracheids.

What are the three classes of Spermatophyta?

The classes of Spermatophyta are Ginkgoopsida, Cycadopsida, Pinopsida, Gnetopsida, and Angiospermae. Ginkgoopsida is just one species; ginkgo or maidenhair tree (Ginkgo biloba). This plant is long extinct in the wild but is grown on Chinese temple grounds as a decorative tree.

What are the economic important of Spermatophyta?

Spermatophyta evolved from spore plants; this is indicated by homology between organs of reproduction in Spermatophyta and vascular spore plants. Spermatophyta play an especially important role in the world’s plant cover and in man’s economic activity.

Why is Spermatophyta important?

ImportanceToday spermatophytes are by far the largest vascular plant lineage, with about270,000 living species. Ecological ImportanceSpermatophytes are important because they perform a process for obtaining foodcalled Photosynthesis. Photosynthesis is the basis of life.

What are the differences between Spermatophyta and Bryophyta?

Answer: Spermatophytes produce seeds while bryophytes do not produce seeds. 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).

What are the similarities between Spermatophyta and pteridophyta?

What is a bryophyte?

Bryophytes are simple plants; they are the simplest plants that grow on land. There are three types of bryophyte. These are mosses, liverworts and hornworts. Bryophyta is the traditional term for this division of non-vascular plants. In some modern classifications the term is restricted to the mosses.

What is a pteridophyte?

A pteridophyte is a vascular plant (with xylem and phloem) that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as ” cryptogams “, meaning that their means of reproduction is hidden.

What are the spermatophytes?

The spermatophytes ( lit. ‘seed-bearing plants’; from Ancient Greek σπέρματος (spérmatos) ‘seed’, and φυτόν (phutón) ‘plant’), also known as phanerogams (taxon Phanerogamae) or phaenogams (taxon Phaenogamae ), comprise those plants that produce seeds, hence the alternative name seed plants. They are a subset of the embryophytes or land plants.

Who coined the term Bryophyta?

The term bryophyta was first suggested by Braun (1964). The division bryophyta is one of the small group among the plant kingdom. It comprises about 960 genera and 24000 sp. (Parihar, 1966). Bryophytes are simplest terestrial plants and commonly known as ambhibians of plant kingdom.
