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.

Which of the following feature is related to pteridophytes?
Pteridophytes are seedless vascular plants. They have true roots, stem, and leaves. Vascular tissues like xylem and phloem are present.
What are the physical characteristics of ferns?
Similar to flowering plants, ferns have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.
What features of leaf you notice in pteridophytes?
The leaves are large in size (megaphylls). They are pinnately compound and are called frond. Young fronds are coiled. Except for aquatic ferns others are all homosporous.
Are cones present in pteridophytes?
Strobili or cones are found in some pteridophytes (like, Selaginella and Equisetum) and all gymnosperms.
What are the 4 classes of pteridophytes give examples?
The four classes of pteridohytes are Psilopsida , Lycopsida, Sphenopsida , pteropsida and example are club-mosses and horsetails . Explanation: pteridohytes are vascular plants and have leaves (known as fronds) , roots and sometimes true stems , and tree ferns have full trunks .
What are pteridophytes describe them?
A pteridophyte is a vascular plant (with xylem and phloem) that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden.
Which feature of pteridophytes helped them to become the first terrestrial plants?
Patridophytes are the first terrestrial plants because there feature posses vascular tissues - xylem and phloem.
Which Pteridophyte is known as water fern?
Azolla (mosquito fern, duckweed fern, fairy moss, water fern) is a genus of seven species of aquatic ferns in the family Salviniaceae. They are extremely reduced in form and specialized, looking nothing like other typical ferns but more resembling duckweed or some mosses.
What are three characteristics of ferns?
Ferns have 3 major parts – the rhizome, the fronds and the reproductive structures called sporangia. The characteristics of each of these 3 parts of the fern plant are used for classification and identification.
What are the characteristics of mosses and ferns?
Mosses: Mosses are small, nonvascular plants that do not have a true root, stem, and leaves and reproduce by the production of spores in stalked capsules. Ferns: Ferns are flowerless, vascular plants with leafy fronds that mainly reproduce by the production of spores.
What is main feature of pteridophytes and discuss its the economic importance?
Economic importance of pteridophytes
Ferns are grown as ornamental plants for their beautiful fronds. The rhizomes and petioles of the fern Dryopteris yield a vermifuge drug. The sporocarps of Marsilea ( a water fern) are used as food by certain tribal people.
Why are pteridophytes described as botanical snake?
Pteridophytes are referred to as botanical snakes as snakes are the first terrestrial animals and so are the Pteridophytes. They are the first true land plants evolving from bryophytes. This is why, sometimes, Pteridophytes are also referred to as 'snakes of the plant kingdom' or 'botanical snakes'.
