Question of Class 11-Pteridophyta : The Salient Features Of Pteridophytes -The Pteridophytes Gk. petron = feather, phyton = plant, Haeckel, 1866 are the spore bearing most primitive vascular plants.. The life cycle of a Pteridophyte comprises of two distinct phases or generations, each of which produces the other. One phase or generation.
what occurs in the life cycle of bryophytes and pteridophytes?
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.

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.

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.

Here, the dominant sporophyte produces spores through meiosis. The gametophyte generation forms gametes by mitosis.
Pteridophyta Characteristics of Pteridophyta, Types Embibe
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 Biology 11
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.
Pteridophyta Characteristics And Features Are Explained In Detail
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:

1. Dominant phase of plant body is a sporophyte. 2. Plant body is differentiated into true stem, leaves and roots. 3. Vascular tissues are present. They are of two types, xylem and phloem. In xylem , true vessels are absent. In phloem, companion cells and sieve tubes are absent.
