Bryophytes are non-vascular plants, without xylem and phloem. On the contrary, pteridophytes are vascular plants with xylem and phloem. ... The dominant phase in pteridophyte is the sporophyte.

What is the difference between bryophytes and bryophytes?

The difference between bryophytes and Bryophyta is one of taxonomic classification. Bryophyta is a taxonomic phylum within the kingdom Plantae.

Which of the following differentiates Pteridophytes from bryophytes and Thallophytes?

Pteridophytes differs from bryophytes and thallophytes in having well developed vascular tissue system. Vascular tissues plays an important role in conducting water and food materials to the plants. Whereas these are absent in bryophytes and thallophytes.

Why are Pteridophytes more advanced than bryophytes?

1. Pteridophytes are better known as the 'Vascular Cryptogams' because they possess vascular tissue for the conduction of water and food material. They occupy an intermediate position between Bryophytes and Phanerogams (seed plants).

How do bryophytes resemble pteridophytes?

Similarities between Bryophytes and Pteridophytes

Ø Both possess distinct Gametophytic and Sporophytic generations. Ø Both groups show heteromorphic alternation of generation. Ø Rhizoids are present in Bryophytes and Pteridophytes. Ø Stomata or pores are present in both groups for gaseous exchange.

How are mosses and pteridophytes different?

Option:B – Pteridophytes have a well developed vascular system and have xylem and phloem, while bryophytes lack vascular tissues. Thus vasculature is a distinguishing feature of pteridophytes and bryophytes.

How gymnosperms differ from bryophytes and Pteridophytes?

Gymnosperms are quite different from bryophytes and pteridophytes. Gymnosperms are vascular, cone-producing plants that produce seeds, while bryophytes are seedless, non-vascular, and produce no cones. Pteridophytes are vascular but are seedless as well.

What are Pteridophytes also called?

Pteridophytes are also called cryptogams. ... 'Cryptogams' is the term used for plants that do not form flowers and seeds. So, it is assumed that their reproduction is hidden as they produce spores.

What is the difference between bryophytes and pteridophytes in terms of reproduction?

Bryophytes: Bryophytes are embryophytes that do not possess a true vascular tissue. Pteridophytes: Pteridophytes are vascular plants that reproduce via spores. Bryophytes: Bryophytes live in moist, shady places. Pteridophytes: Pteridophytes live in terrestrial environments.

Which of the following best compares bryophytes and pteridophytes?

Which of the following best compares bryophytes and pteridophytes? Bryophytes are nonvascular plants, and pteridophytes are seedless vascular plants.

What are the main characteristics of bryophytes?

General Characteristics of Bryophytes:

• Plants occur in damp and shaded areas.
• The plant body is thallus like, i.e. prostrate or erect.
• It is attached to the substratum by rhizoids, which are unicellular or multicellular.
• They have a root-like, stem-like and leaf-like structure and lack true vegetative structure.

What do bryophytes and pteridophytes have in common?

Similarities Between Bryophytes And Pteridophytes

Both plants consist of the heteromorphic alternation of generations. They are multicellular sporangia. The cuticle is present in both the plants. Sexual reproduction takes place due to the presence of oogamous.

Why are pteridophytes limited?

The spreading of living pteridophytes is limited and restricted to narrow geographical region because: a) Gametophytic growth needs cool, damp and shady places. b) It requires water for fertilization.

Why bryophytes are dependent on water?

Bryophytes are called amphibians of plant kingdom because they complete their vegetative phase on land but water is necessary for their reproductive phase. ... It also helps in the transfer of sperms to the archegonium that make water essential for completion of life cycle of bryophytes.

What is required for transport of male gametes in bryophytes and pteridophytes?

- In pteridophytes and bryophytes, water is essential for the transport of male gametes. ... - To enter the female gamete, the male gamete requires water through which it can move. In many basic plants, water acts as the channel by which gamete transfer takes place. Thus, the correct answer is option (D) water.

Is asexual reproduction absent in bryophytes?

Many dioecious bryophytes propagate by clonal growth of gametophytes, with sexual reproduction rare or absent. In some taxa, sporophytes are unknown. Most ferns, by contrast, propagate as perennial sporophytes and possess gametophytes that lack means of asexual reproduction.

How do sperm get out of the Antheridium?

When a mature antheridium is moistened the cells at the apex absorb water, swell and finally burst or open in some way. The sperm mass inside a mature antheridium is under pressure. So, once an antheridium has opened, the sperm mass is forced out.

Do all bryophytes have Protonema?

Moss spores germinate to form an alga-like filamentous structure called the protonema. ... These give rise to gametophores, stems and leaf like structures. Bryophytes do not have true leaves (megaphyll. Protonemata are characteristic of all mosses and some liverworts but are absent from hornworts.

Which of the following best compares bryophytes and Pteridophytes 4 points?

Which of the following best compares bryophytes and pteridophytes? Bryophytes are nonvascular plants, and pteridophytes are seedless vascular plants.

Which of the following best compares gymnosperms and Pteridophytes?

Which of the following best compares gymnosperms and pteridophytes? They both produce seeds, but gymnosperms produce flowers and fruit, while pteridophytes do not.
