Answer 1

Answer:

What is Thallophyta

Thallophyta is phylum that includes seedless plants and plant-like organisms. This consists of algae, fungi, lichens, and bacteria. Thus, Thallophyta is a polyphyletic group of non-mobile organisms, whose plant body is described as a thallus. Most Thallophytes can be found in wet habitats. All Thallophytes are autotrophic and produce their own food. The food is stored in the form of starch. Thallophytes do not have a vascular system. They consist of single-celled sex organs.The two subdivisions of Thallophyta are Euthallophyta and Myxothallophyta. The Euthallophyta consists of algae, fungi, lichens, and bacteria. Algae are chlorophyll-bearing organisms that mostly live in aquatic environments. Fungi are heterotrophic organisms. They live with algae forming lichens. In lichens, the fungi live as saprophytes. Cyanobacteria contain chlorophyll, and hence they are called as the blue-green algae. The myxothallophyta consist of slime molds.

What is Bryophyta

Bryophyta refers to the small, flowerless plants. This consists of liverworts, mosses, and hornworts.  Bryophytes live in moist, shady environments. Their plant body is not differentiated into true stem, root, and leaves. However, they show stem-like, root-like, and leaf-like structures. The root-like structures are called rhizoids; they attach the plant body to the substrate. Bryophytes also do not have a true vascular system.  Bryophyta shows the alterations of generations with a prominent gametophyte. The sporophyte produces spores. The liverworts consist of thallose leaf-like structures. Mosses are the most widely spread bryophytes with follilose leaf-like structures. The hornworts produce horn-like sporophytes.

What is Pteridophyta

Pteridophyta refers to the flowerless plants whose plant body is differentiated into true stem, root, and leaves. Pteridophyta consists of ferns, horsetails, quillworts, club mosses, and spike mosses. These plants consist of a true vascular system. Pteridophytes are a type of highly organized plants that live in dry, terrestrial habitats.Pteridophyta shows the alterations of generations with a prominent sporophyte. The main reproduction method of the Pteridophyta is the production of spores.
