What is the function of Pteridophytes?

Pteridophytes. Pteridophtyes are a phylum of plants. They are the vascular plants (those having xylem and phloem tissues) that reproduce by releasing spores rather than seeds, and they include the highly diverse true ferns and other graceful, primarily forest-dwelling plants.

What do you mean by protostele and siphonostele?

Definition. Protostele refers to a type of stele in which the vascular tissue in the stem forms a solid core, with no central pith or leaf gaps while siphonostele refers to a type of stele in which the vascular tissue in the stem forms a cylinder surrounding a central pith and possessing leaf gaps.

Which is the type of protostele?

There are three basic types of protostele: haplostele (FIG. 7.32), actinostele, and plectostele (FIG. 7.33). In a haplostele, the xylem is circular in cross section or cylindrical in three dimensions; phloem is immediately outside the xylem.

What is protostele example?

Definition of protostele : a stele forming a solid rod with the phloem surrounding the xylem.

What is the structure of pteridophytes?

Pteridophytes (ferns and lycophytes) are free-sporing vascular plants that have a life cycle with alternating, free-living gametophyte and sporophyte phases that are independent at maturity. The body of the sporophyte is well differentiated into roots, stem and leaves. The root system is always adventitious.

What are pteridophytes PDF?

Pteridophytes (vascular cryptogams or ferns and fern allies) comprise about 12 000 species. of primitive vascular plants; they do not produce flowers or seeds and reproduce instead via. spores. They occur in most terrestrial habitats and also in some aquatic communities.

What are the main features of pteridophytes?

The general characteristics of Pteridophytes are:

• They are seedless.
• They are multicellular.
• They reproduce through spores.
• They are independent and free-living organisms.
• They have a well-differentiated plant body into root, stem and leaves.

What are pteridophytes characteristics?

Primary characteristics of Pteridophytes are as follows: They are seedless, vascular plants that show true alternation of generations. Furthermore, the sporophyte has true roots, stems and leaves. They reproduce by spores, which are developed in sporangia. They may be homosporous or heterosporous.

What are characteristics of pteridophytes?

What are the classification of Pteridophyte?

Pteridophytes are the first terrestrial vascular plants. Carolus Linnaeus classified them under the group cryptogamae. Pteridophytes occupy a transitional position between bryophytes and spermatophytes. They do not produce flowers and seeds, hence they are also called Cryptogams.

How to create a functional resume?
