Question

The plant which is differentiated into roots, stems, and leaves but does not bear flowers and seeds are classified as
(a)Thallophytes
(b)Bryophytes
(c)Pteridophytes
(d)Hydrophytes

Answer 1

Hint: It is free-sporing vascular plants that have a life cycle with substituting, free-living gametophyte, and sporophyte stages that are autonomous at development. The body of the sporophyte is all around separated into roots, stem, and leaves. The root system is always adventitious.

Complete answer
Pteridophytes are vascular plants and have leaves (known as fronds), roots, and once in a while evident stems, and tree greeneries have full trunks. For example, ferns, horsetails, and club mosses. Fronds inside the biggest types of plants can arrive at around six meters in length. Many ferns from tropical rain forests are epiphytes, which suggests they only grow on other plant species. Their water comes from the sodden air or from precipitation running down branches and tree trunks. There are some simply sea-going greeneries like an amphibian plant or water velvet (Salvinia molesta) and mosquito plants (Azolla species). Thallophytes and bryophytes aren't separated into roots, stems, and leaves. Hydrophytes are separated into roots, stems, and leaves and bear blossoms and seeds.

Additional information
Pteridophyta Classification
Pteridophyta is classified into four main classes:
Psilopsida
They are the most primitive.
The stem is photosynthetic and dichotomously branched.
Rhizoids are present.
Leaves are mostly absent.
The sporophyte is a homosporous synangium.
Examples- Psilotum and Tmesipteris.
Lycopsida
They are commonly known as club moss.
Well-differentiated plant body with adventitious root, stem, rhinophores, and leaves.
The sporophyte is homosporous or heterosporous.
Examples- Selaginella, Lycopodium.
Sphenopsida
Commonly known as horsetail.
It is well-differentiated from the plant body with roots arising from nodes of the underground rhizome, stem, and scaly leaves.
Homosporous, sporangia are borne on strobila.
Examples- Equisetum.
Pteropsida
Commonly known as a fern.
Well-differentiated plant body with roots, stem, and leaves.
The sporophyte is homosporous or heterosporous.
Antherozoids are multiflagellate.
Examples- Pteris, Dryopteris, Adiantum

So the correct answer is ‘Pteridophytes’.

Note: The sexuality of pteridophytic gametophytes can be delegated follows:
Dioicous: the individual gametophyte is either a male creating antheridia and sperm or female delivering archegonia and egg cells.
Monoicous: every individual gametophyte may produce both antheridia and archegonia and it can function both as a male also as a female.
Protandrous: the antheridia matures before the archegonia.
Protogynous: the archegonia matures before the antheridia.
