Pteridophytes (Spore Producing Plants Ferns and More) •
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.

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 Class Eleven Biology
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.

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:

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?

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.

Pteridophyta (Life Cycle) YouTube
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 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.
