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.

A nonvascular plant is any species of plant which does not have specialized vascular tissues. This includes everything from higher structured forms of green algae, which have plant-like characteristics, to mosses (Bryophyta), liverworts (Marchantiophyta) and hornworts (Anthocerotophyta). Members of these groups, which live in both marine environmen...
All plants and some algae exhibit an alternation of generations life cycle. In this cycle, a gametophyte gives rise to gametes. The gametophyte is a haploid organism, containing only one set of DNA. The gametes, therefore, are produced via mitosis. When these gametes fuse, they create a zygote, which is a new diploid organism. This zygote will grow...
Moss
Moss is a nonvascular plant found worldwide. Moss is often one of the only plant types to colonize certain areas, including areas with poor soil. Moss typically grows in wet, damp areas. This is not always the case. Moss has colonized most environments, from the cold Artic to the dry desert. There are approximately 12,000 species of moss. Some moss species are nearly microscopic, while others can grow over a foot tall. Mosses, being a nonvascular plant, are mostly limited in height beyond thi...
Liverwort
Where moss grows in small branching structures, and many organisms get packed in a larger mat or bundle, liverwort grows as small, individual leaf-like structure. The thallus, as it is called, is the dominant gametophyte. The thallus will produce specialized organs, to house the sporophyte. Liverwort and hornwort are almost indistinguishable, besides some differences in their thallus and the structure of their sporophytes. However, genetic evidence has revealed that liverwort and hornwort, wh...
Hornwort
Commonly mistaken as liverwort, hornwort is a closely related group of nonvascular plant species. Like mosses and liverworts, hornworts exist as a dominant gametophyte form. Hornworts, because of the way that they combine their chloroplasts with other organelles, are thought to be more closely related to certain species of algae than other land plants. While hornwort, liverwort, and mosses used to all belong to the Bryophyta, the hornworts and liverworts have been given their own divisions. T...
1. A scientist is trying to grow a nonvascular plant which is 20 feet tall. Why is this unlikely? A. Sounds reasonable enough! B. Water pressure C.A nonvascular plant cannot retain water 2. The following is a list of features of vascular plants. Which of the features is shared by a nonvascular plant? A. Organized, multicellular structure and the ab...
Learn what a nonvascular plant is, how it differs from a vascular plant, and what examples of nonvascular plants exist. Find out how nonvascular plants reproduce, colonize, and survive in various environments.
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.
Jul 16, 2018 · Learn about the three main divisions of non-vascular plants: mosses, liverworts, and hornworts. Find out how they lack vascular tissue, reproduce, and survive in moist habitats.

Mar 21, 2022 · Learn about non-vascular plants, the first plants to evolve without vascular tissues, roots, leaves, and shoots. Find out how they reproduce, where they live, and what groups they belong to.
Nonvascular Plants. 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 ecology.
Jun 13, 2024 · Bryophytes are plants that lack vascular tissue and include mosses, hornworts, and liverworts. They have an alternation of generations, a life cycle with gametophyte and sporophyte, and diverse forms and habitats.
