Pteridophytes or Pteridophyta, in the broad interpretation of the term (or sensu lato), are
vascular plants
(plants with xylem and phloem) that reproduce and disperse via spores. Because they produce neither flowers nor seeds, they are referred to as cryptogams.
Which is a Pteridophyte?
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.
What are pteridophytes Class 11?
The pteridophytes are found in
cool, damp, shady places
. The main plant body is a sporophyte which is differentiated into true root, stem and leaves, possess well-differentiated vascular tissues.
What is pteridophyta classification?
Pteridophytes are the
“spore bearing vascular plants”
and also called as seedless vascular plants belong to the cryptogams. … Tracheophyta are further divided into four main groups : Psilopsida, Lycopsida, Sphenopsida and Pteropsida. But it is not certain whether these are divisions or classes.
Which of the following traits belong to the phylum pteridophyta?
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 is called Sporophyll?
A sporophyll is
a leaf that bears sporangia
. Both microphylls and megaphylls can be sporophylls. In heterosporous plants, sporophylls (whether they are microphylls or megaphylls) bear either megasporangia and thus are called megasporophylls, or microsporangia and are called microsporophylls.
What are the 4 characteristics of Kingdom Plantae?
- They are eukaryotic and multicellular.
- Their cells have cellulose walls.
- Majority have transport system.
- They have photosynthesis hence autotrophic.
- Reproduction is both asexual and sexual.
- They show alternation of generation.
Who are Pteridophytes give examples?
Pteridophytes are vascular plants and have leaves (known as fronds), roots and sometimes true stems, and tree ferns have full trunks. Examples include
ferns, horsetails and club-mosses
.
Why Pteridophytes are called Tracheophytes?
Pteridophytes are called tracheophytes
because they have vascular tissue
. Note: Pteridophytes are a type of vascular plant that reproduces by means of spores. They are also known as cryptogams because they do not contain flowers or seeds.
What is the common name of Pteridophytes?
| Taxonomic Category Scientific Name Common Name | Kingdom Plantae Green plants | Division Pteridophyta Ferns |

What are the 4 classes of Pteridophytes give examples?
Answer: 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 the 2 divisions of Pteridophytes?
Due to discovery of the fossil plants, the classification of Pteridophytes has undergone vast changes in the recent past. Older taxonomists divided the vascular plants in two divisions—
Pteridophyta (primitive vascular plants with absence of seeds) and spermatophyta (presence of seeds)
.
What is difference between Sporophyte and Gametophyte?
| Sporophyte Gametophyte | Sporophytes have two sets of chromosomes. These have a single set of chromosomes. | These reproduce asexually. These reproduce sexually. |

Is Spermatophyta a phylum?
noun plural (Bot.)
A phylum embracing the highest plants
, or those that produce seeds; the seed plants, or flowering plants. … All the Spermatophyta are heterosporous; fertilization of the egg cell is either through a pollen tube emitted by the microspore or (in a few gymnosperms) by spermatozoids.
Is phylum a Pterophyta?
The largest group of living seedless vascular plants—and probably the most familiar—are the ferns with about 12,000 species, over two‐thirds of which are tropical. Ferns are an ancient group.
