Difference Between Bryophytes and Pterophytes

Bryophytes are non-vascular plants, without xylem and phloem. They reproduce by gamete formation. For eg., mosses, liverworts and hornworts. On the contrary, pteridophytes are vascular plants with xylem and phloem.

What is common between bryophytes and Pteridophytes?

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.

What is the difference between bryophytes and ferns?

The key difference between bryophytes and ferns is that the bryophytes are nonvascular plants while ferns are vascular plants. In simple words, bryophytes lack xylem and phloem while xylem and phloem are present in ferns. Furthermore, bryophytes do not have true leaves while ferns have true leaves.

What is the difference between Pteridophytes and gymnosperms?

Pteridophytes are mostly herbs or shrubs. Majority of Gymnosperms are trees. Gametophyte is completely dependent on sporophyte and they are physically connected. Pteridophytes grow in mesophytic conditions.

What is the difference between Thallophyta and pteridophyta?

The key difference between thallophyta and pteridophyta is that the thallophyta is a group of non-mobile organisms that possess a thallus-like undifferentiated body while the pteridophyta is a group of vascular plants that possess a plant body differentiated into true stem, roots, and leaves.

Do bryophytes have motile sperm?

Like the bryophytes, ferns and fern allies are still restricted to moist habitats. Their flagellated sperm need a thin film of water to swim between the antheridium and the archegonium. ... This basic strategy of a free-swimming sperm and a non-motile egg is shared by plants, animals, and algae.

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 is the life cycle of bryophytes?

Like all land plants (embryophytes), bryophytes have life cycles with alternation of generations. In each cycle, a haploid gametophyte, each of whose cells contains a fixed number of unpaired chromosomes, alternates with a diploid sporophyte, whose cell contain two sets of paired chromosomes.

Are ferns bryophytes?

Liverworts, hornworts, and mosses are the examples of bryophytes. These are non-vascular plants i.e. do not contain xylem and phloem tissues.

How do bryophytes reproduce asexually?

Bryophyte reproduction happens in two ways, like with other plants. ... Asexual reproduction occurs when a sporophyte releases spores, and sexual reproduction happens when gametes fuse and form a zygote. When a bryophyte spore settles somewhere, it grows into a gametophyte. Gametophytes are green and leafy, but small.

What is the meaning of Pteridophytes?

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 is the definition of gymnosperms?

Medical Definition of gymnosperm

: any of a class or subdivision (Gymnospermae) of woody vascular seed plants (as conifers or cycads) that produce naked seeds not enclosed in an ovary and that in some instances have motile spermatozoids — compare angiosperm.
