Non-vascular plants are plants without a vascular system consisting of xylem and phloem. Instead, they may possess simpler tissues that have specialized functions for the internal transport of water. [citation needed] Non-vascular plants include two distantly related groups: treat as three separate land-plant divisions, namely: Bryophyta ...

Hornworts alternate between a gametophyte phase and a sporophyte phase in their life cycle. The thallus is the plant gametophyte and the horn-shaped stalks are the plant sporophytes. Male and female sex organs (antheridia and archegonia) are produced deep within the gametophyte. Sperm produced in male antheridia swims through the moist environment ...
Non-vascular plants, or bryophytes, are plants that lack a vascular tissue system. They have no flowers, leaves, roots, or stems and cycle between sexual and asexual reproductive phases.The primary divisions of bryophytes include Bryophyta (mosses), Hapatophyta (liverworts), and Anthocerotophyta (hornworts).Due to the lack of vascular tissue, non-vascular plants typically remain close to the ground and are found in moist environments. They are dependent upon water to transport sperm for fertilization.The green body of a bryophyte is known as the thallus, and thin filaments, called rhizoids, help to keep the plant anchored in place."Bryophytes, Hornworts, Liverworts, and Mosses - Australian Plant Information."

Liverworts are tiny nonvascular plants that have leaf-like, lobed, or ribbon-like photosynthetic tissues rather than leaves. Their rhizoids are very fine, they lack stems, and they are generally less than 10 centimeters (4 inches) tall. They often grow in colonies that carpet the ground. Hornworts are minute nonvascular plants, similar in size ...
Mar 21, 2022 · The main characteristics of non-vascular plants are the absence of vascular tissues, the xylem, and the phloem. It means non-vascular plants do not have the mechanism required for transporting food and water at greater heights and thus cannot grow tall like vascular plants. Hence, there is a difference between vascular and non-vascular plants.

May 2, 2024 · Bryophyte, traditional name for any nonvascular seedless plant—namely, any of the mosses (division Bryophyta), hornworts (division Anthocerotophyta), and liverworts (division Marchantiophyta). Most bryophytes lack complex tissue organization, yet they show considerable diversity in form and.
Feb 22, 2021 · Bryophytes is the informal group name for mosses, liverworts and hornworts. They are non-vascular plants, which means they have no roots or vascular tissue, but instead absorb water and nutrients from the air through their surface ( e.g., their leaves). Most of them only grow a few centimeters in height, and since they don't need roots, they ...
