Pteridophytes Biology 11
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.

The life cycle of a Pteridophyte comprises of two distinct phases or generations, each of which produces the other. One phase or generation.

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.

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 (Life Cycle) YouTube
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.

Here, the dominant sporophyte produces spores through meiosis. The gametophyte generation forms gametes by mitosis.

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.

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.
