What are the characteristics of phylum Pterophyta?
Primary characteristics of Pteridophytes are as follows: They are seedless, vascular plants that show true alternation of generations. Furthermore, the sporophyte has true roots, stems and leaves. They reproduce by spores, which are developed in sporangia. They may be homosporous or heterosporous.
What are the distinguishing features of Leptosporangiate and Eusporangiate development in seedless vascular plants?
Eusporangiate: large sporangium develops from many initial cells and produces many spores. 2. Leptosporangiate: small sporangium develops from single initial cell and produces small definite no. of spores(<128).

How are the four phylum of Pteridophyta classified?
Classification of Pteridophyta. Pteridophyta includes in Plantae kingdom and have four phylum, they are Psilophyta, Lycophyta, Equisetophyta and Pterophyta. It also divided into four classes; Psilophytinae (ancient fern), Lycopodinae (wire fern), Equisetinae (horse tail fern), and Filicinae (Real fern) Class of Psilophytinae.
What are the distinguishing features of the phylum Lycophyta?
Phylum Lycophyta: Club Mosses and More. The distinguishing features of the lycophytes are the arrangement of their vascular tissues and their leaves—microphylls with only a single vascular strand. The sporangia on the modern plants are kidney-shaped, like those of the ancestral forms, and borne on sporophylls clustered in strobili.
What are the characteristics of a pterophyta plant?
General characteristics of Pterophyta. Since Pterophyra have lignified xylem vessels and phloem vessels they belong to the vascular plants, in contrast to algae (e.g. Laminaria, Volvox, Polysiphonia) and mosses (e.g. Marchantia, Funaria). Pterophyta may also develop stems, often as rhizomes, true leaves, called frond, and -simple- roots.
What kind of life cycle does a pteridophyte have?
The life cycle of pteridophytes is probably best exemplified by the general life cycle of the fern. Ferns have a life cycle that alternates from a mature adult to an immature fern. We use the term sporophyte for the mature adult, and gametophyte for the immature baby fern.
