The description of a plant is divided into four sections: roots, stems, leaves, and flowers. Based on this knowledge, the plant world is classified into two categories: flowering plants and non-flowering plants. Non-flowering plants are ones that cannot produce flowers. These plants are also classified as bryophytes and pteridophytes. Here’s how to distinguish between bryophytes and pteridophytes.
Bryophytes-:Bryophytes are the most fundamental plants that thrive in moist terrestrial conditions. There are no true roots, simply rhizoids that serve as anchors. Plants, for example, are known as bryophytes.
Pteridophytes-: Pteridophytes are plants that grow in wet, dark circumstances. This plant is made up of a leaf, suitable roots, and underground stalks. The leaf has been precisely chopped into little bits. Plants such as ferns are examples of pteridophytes.
Angiosperms and Gymnosperms are two types of blooming plants. These plants share stems, leaves, roots, enough vascular tissues for transportation, and flowers and fruits.
Bryophytes include plants such as liverworts, hornworts, and mosses. These plants have no xylem or phloem tissues. They are known as non-vascular plants. Pteridophytes include spikemosses, clubmosses, ferns, and quillworts. They contain xylem and phloem tissues.
Bryophytes
The term ‘bryophytes’ refers to plants that lack real vascular tissue. It is a common name for plants or embryophytes. Because they lack xylem and phloem, these plants are referred to as “non-vascular plants.”
The presence of a dominant gametophyte causes the creation or generation of gametes. They cannot, however, generate blooms or seeds. A bryophyte’s body is made up of rhizoids that act as anchors rather than true roots, stalks, and leaves. They reproduce through spores and transport unbranched sporophytes.
Bryophytes include mosses, liverworts, and hornworts. They prefer a damp atmosphere for growth and are small, yet they may thrive in a dry environment as well. It is significant because it delivers water and nutrients to other plants in an environment dominated by bryophytes.
Pteridophytes
Pteridophytes plants are sometimes known as cryptograms since they do not produce flowers or seeds. Because they have xylem and phloem tissues, these plants are categorised as vascular plants. Fronds represent the leaves, true stems represent the true stems, and roots represent the roots.
Pteridophytes contain the largest fern species, fronds, which can grow to be up to six metres long. These are true ferns with a diverse range of species. To propagate and reproduce these plants, spores are utilised instead of seeds. These plants thrive in conditions that are moist, dark, gloomy, cool, and damp.
As they can generate gametes, these plants are known as gametophytes. A plant’s structure is described by its roots, stems, and leaves. Pteridophytes include, among other things, club mosses, ferns, spikemosses, and quillworts. Pteridophytes are seed plants related to angiosperms, conifers, and other seed plants.
Bryophytes and Pteridophytes Share Characteristics
1.Both plants are constructed up of heterotrophic generations that alternate.
2.They are sporangia with many cells.
3.The cuticle is found in both plants.
4.Sexual reproduction occurs due to the presence of oogamous.
They consist of flagellated male gametes and non-motile female gametes.
6.Because of the lack of siphonogamy, internal fertilisation is required.
Difference Between Bryophytes And Pteridophytes
Character | Bryophytes | Pteridophytes |
Definition | Bryophytes are plants with a leafy or thalloid body | Roots, stems, and leaves make up pteridophytes. |
Vascular Tissue | There is no vascular tissue present. | There is vascular tissue present. |
Vasculature System | Bryophytes lack a vascular system, which means that xylem and phloem are lacking. | Pteridophytes have good vasculature, which implies they have xylem and phloem. |
Roots | Plants do not have roots; instead, they contain rhizoids, which aid in anchoring. | The roots of these plants can be seen. |
Stems or leaves | There are no actual stems or leaves on this plant | True stems and leaves are seen in this plant. |
Antheridium | The antheridium has been stalked. | Antheridium is a sessile organism. |
Archegonium | Archegonium, whose neck is made up of six rows of cells, is a common sight | There is a partially embedded archegonium with only four rows of cells in its neck |
Dominating Part | Gametophyte dominates in bryophytes | The sporophyte is dominant in pteridophytes |
Phase of sporophyte | The sporophytic phase is entirely dependent on the gametophytic phase. | The sporophytic phase is a self-contained autotrophic phase |
Type of cell | Haploid cells are seen in bryophytes. | Diploid cells are found in pteridophytes. |
Examples | Mosses, liverworts, and hornworts are all examples of mosses | Spikemosses, clubmosses, ferns, and quillworts are examples of mosses. |
Conclusion
We conclude that they contain enclosed reproductive systems but don’t generate flowers or seeds, instead relying on spores to proliferate. Fungus, lichens, and algae are examples of thallophytes, which grow in water. They have a reproductive system that is hidden. Pteridophytes do not produce blooms or seeds because their reproductive organs are hidden.
