Their leaves are called fronds. The female sex organ is single-celled oogonium. Pteridophytes also consist of a true vascular system. The sex organs are unicellular, and when multicellular every cell forms a gamete. Figure 1: The life cycle of bryophytes Classification of Bryophytes Marchantiophyta liverworts , Bryophyta mosses and Anthocerotophyta hornworts are the three divisions of bryophytes.
The sporophyte of pteridophytes is most prominent. Bryophyta:Liverworts, mosses, and hornworts are examples of Bryophyta. The is dominant in bryophytes whereas the sporophyte is dominant in pteridophytes. Archegonia with long neck having 6 vertical rows of cells. Bryophyta:Bryophyta mainly lives in aquatic environments.
Nevertheless, they might likewise be as thoughts boggling as blooming vegetation. The gametophyte and sporophyte are independent. Many ferns in epical rain forests are epiphytes that grow on the trunks of other trees. In Smith's molecular phylogenetic study the ferns are characterised by origin in the , usually in shoots, a pseudoendospore, , and with 30-1000. True vascullar system is present. Spores are disposed by wind. True vascular system is absent.
True vascular system is present. In each chlorophyllous cell many well developed chloroplasts are present. Mosses are the most widely spread bryophytes with follilose leaf-like structures. Plant body does not have true roots, stems and leaves but shows root like and leaf-like structures. In Pteridophyta, the body is differentiated into stem, leaves as well as root. Habitat Thallophyta: Thallophyta lives in aquatic environments, on or within plants, on snow, and on rocks. Pteridophytes:-it include horstell and ferns.
The main plant body is a gametophyte and haploid. Before sharing your knowledge on this site, please read the following pages: 1. Sexual reproduction is only oogamous. Difference Between Thallophyta Bryophyta and Pteridophyta Definition Thallophyta:Thallophyta refers to seedless and flowerless organisms consisting of algae, fungi, lichens, and bacteria. Sporophyte is differentiated to root, stem and leaves and is initially dependent on gametophyte. Archegonia with short neck having 4 vertical rows of cells. Mosses or bryophytes are simplest plants having no true roots, rhizoids for anchorage and grow in the damp terrestrial land.
Terrestrial, present in damp places. These are used for medicinal purposes and as soil-binders. Conclusion In the given article we discussed the differences and similarities among bryophytes and pteridophytes. Pteridophyta consists of ferns and their relatives. The life cycle of thallophytes has two independent generations. Bryophyta:Bryophyta forms an embryo after fertilization. Main Difference — Thallophyta Bryophyta vs Pteridophyta Thallophyta, Bryophyta, and Pteridophyta are the three phyla of , which is a subkingdom of Plantae.
So, a greenery is a bryophyte, a liverwort is a bryophyte, and a hornwort is a bryophyte. The gametophyte is multicellular and microscopic. Embryo is formed after fertilization. Bryophytes are also called 'amphibians' of the plant kingdom. Therefore, they are considered as amphibians in the kingdom of Plantae. Plant body does not have true roots, stems and leaves but shows root like and leaf-like structures.
Archegonia Neck Bryophytes:The neck of the archegonia in bryophytes is long, containing six vertical rows of cells. Habitat: Thallophytes: Thallophytes are mainly aquatic. Modern studies of the land plants agree that all pteridophytes share a common ancestor with seed plants. Plant body does not have true roots , stems and leaves but shows root like and shoot like structures. Vascular tissues and mechanical tissues are present. The sporophyte is independent, diploid and differentiated into roots, stems and leaves. No embryo formation takes place after fertilization.
The present post discusses the Similarities and Differences between Bryophytes and Pteridophytes with a comparison table. Embryo is formed after fertilization. Crown ferns are shown in figure 4. Plant body is differentiated into stem, leaves and roots. Ø Fertilization and embryo development is similar in both Bryophytes and Pteridophytes. Below we will discuss the general difference between bryophytes and pteridophytes.
Young leaves show circinate vernation. Few examples are Spikemosses, clubmosses, ferns, quillworts. Pteridophytes differ considerably in measurement. Bryophytes: In bryophytes, the zygote is multicellular. Archegonia with short neck having 4 vertical rows of cells. Water is absorbed by the plant body itself and conducted internally in the plant body. Characters Thallophyta Bryophyta Pteridophyta Habitat Mostly aquatic fresh and marine- both forms exist.
