View Solution Type of vascular bundle: (i) Concentric (ii) Amphicribal (iii) Mesarch condition and closed. Note: Secondary growth is absent (due to absence of cambium) in pteridophytes but exceptionally secondary growth is present in stem of Isoetes. 1 Crore+ students have signed up on EduRev. Have you?

Plant Life Cycles and Alternation of Generations You can download Plant Kingdom Cheat Sheet by clicking on the download button below Reproduction in Pteridophytes Pteridophytes show a true alternation of generations. Here, the dominant sporophyte produces spores through meiosis. The gametophyte generation forms gametes by mitosis.

Life cycle of a Pteridophyte (fern). Meiosis occurs within sporangia
Pteridophyta is classified into four main classes: Psilopsida They are the most primitive. The stem is photosynthetic and dichotomously branched. Rhizoids are present. Leaves are mostly absent. The sporophyte is homosporous synangium. Examples- Psilotum and Tmesipteris. Lycopsida They are commonly known as club moss.
Pteridophytes Biology 11
Pteridophyta Life Cycle Pteridophytes have generations that alternate. Their life cycle is similar to that of seed-bearing plants; however, unlike mosses and seed plants, pteridophytes have separate and free-living generations of haploid gametophyte and diploid sporophyte.

Life Cycle Of Pteridophytes bartleby
Description. 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 systems is always adventitious.
Pteridophytes (Spore Producing Plants Ferns and More) •
Pteridopsida (true ferns) have more than 10,000 species and make up the majority of living monilophytes (all classes of Pteridophyta except lycophytes). Their leaves are called fronds because of apical growth; young leaves are coiled into fiddleheads (Figure 6.2.2 6.2. 2 ). True ferns are megaphyllous: their leaves originated from flattened.
what occurs in the life cycle of bryophytes and pteridophytes?
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. More than 12,000 species of Pteridophytes are found on Earth.

The unique character of the life cycle of Pteridophyte is - Independent alternation of generation i.e sporophyte and gametophyte are separate to each other..

BIOLOGY Life Cycle of Pteridophyta
Their life cycle is similar to seed-bearing plants, however, the pteridophytes differ from mosses and seed plants as both haploid gametophyte and diploid sporophyte generations are independent and free-living. The sexuality of pteridophytic gametophytes can be classified as follows:
Pteridophyta Characteristics And Features Are Explained In Detail
The lifecycle of a pteridophyte begins with a sporophyte that bears sporangia, which are subtended by leaf-like appendages called sporophylls. The sporangia produce spores in spore mother cells by meiosis that germinates into the prothallus, a small, multi-cellular, free-living, photosynthetic and haploid gametophyte.
