Difference between Bryophytes and Pteridophytes (Comparison Table)

Difference between Pteridophytes and Bryophytes

Bryophytes vs Pteridophytes
(Similarities and Difference between Bryophytes and Pteridophytes)

Bryophytes are most primitive land plants predominantly grow in moist and shaded places. Bryophytes are known as the Amphibians of Plant Kingdom since water is essential for the completion of their life cycle. The Bryophytes includes three groups of plants such as Liverworts, Hornworts and Mosses.

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).

Bryophytes and Pteridophytes are evolutionarily related and they show many similarities. The present post discusses the Similarities and Differences between Bryophytes and Pteridophytes (with a comparison table).

Similarities between Bryophytes and Pteridophytes

Ø  Both Bryophytes and Pteridophytes are land plants.

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.

Similarities and Difference between Bryophyte and Algae (A Comparison Table)

difference between bryophytes and algae

Algae Vs Bryophytes

Bryophytes are the most primitive land plants. They are immediate between aquatic and terrestrial life. Even though bryophytes are well adapted for the land life they require the presence of water for the completion of their life cycle. Most of the evolutionary biologists believe that bryophytes were originated from Algae. This belief is strongly supported by the similarities of many characters in algae and bryophytes. This post describes the similarities and major difference between algae and bryophytes.

Similarities between Algae and Bryophytes

(1).      In both groups the plant body is thalloid and undifferentiated.

(2).      Plant body is not differentiated into root, stem and leaves in both groups

(3).      Gametophytic generation is the prominent phase in life cycle in both groups

(4).      True roots are absent in both groups of algae and bryophytes

(5).      Both groups are autotrophic in nutrition

(6).      In both algae and bryophytes major photosynthetic pigments are chlorophyll a, b and carotenes

Characteristics of Bryophytes (Life Cycle and Reproduction of Phylum Bryophyta)

Characters of Bryophytes

Mosses and Liverworts General Characteristics (Key points with PPT)

Ø  Bryophytes are the most simplest and most primitive land plants

Ø  Name bryophyte is derived from two words; ‘Bryon’ = moss; ‘phyton’ = plant

Ø  At present the phylum Bryophyta includes  ~ 960 genera and ~ 24000 species

Habit and Habitat of Bryophytes

Ø  They are cosmopolitan in distribution

Ø  Bryophytes are quite uncommon in marine environments

Ø  Bryophytes are terrestrial plants but require water at every stages in their life cycle

Ø  They grow usually in moist and shady places

Ø  They fail to complete its life cycle in the absence of water

Ø  Few bryophytes are truly aquatic and underwater forms(example Riccia fluitans)
