Non-vascular plants play crucial roles in their environments. They often dominate certain biomes such as mires, bogs and lichen tundra where these plants perform primary ecosystem functions. Additionally, in bogs mosses host microbial communities which help support the functioning of peatlands.

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."

Nonvascular plants are called bryophytes. Nonvascular plants include liverworts, hornworts, and mosses. They lack roots, stems, and leaves. Nonvascular plants are low-growing, reproduce with spores, and need a moist habitat.
Feb 22, 2021 · 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).
13 The Non-Vascular Plants and Seedless Vascular Plants. By the end of this chapter you will be able to: Describe the distinguishing traits of the three types of bryophytes. Identify the new traits that first appear in seedless vascular plants. Describe the major classes of seedless vascular plants.
Mar 21, 2022 · Non-vascular plants are plants devoid of a vascular system consisting of xylem and phloem. They are also devoid of roots , shoots, and leaves and grow from spores. However, some non-vascular plants possess specialized tissues to conduct water and minerals within the plant body.
