Detailed explanation-1: -Bryophytes such as mosses and algae are non-vascular plants. They do not possess true roots, stems and leaves. Xylem and phloem are absent.
Detailed explanation-2: -Algae are a large group of generally aquatic plants. Like bryophytes, algae are nonvascular: They lack the xylem and phloem tissues that transport fluids and nutrients internally. They do not have leaves, roots or flowers, nor do they have rhizoids or leaflike structures like some nonvascular plants.
Detailed explanation-3: -Nonvascular plants (often referred to collectively as the bryophytes) include three groups: the mosses (Bryophyta), approximately 15, 000 species; liverworts (Hepaticophyta), approximately 7500 species; and hornworts (Anthocerophyta), approximately 250 species (Table 1).
Detailed explanation-4: -Mosses and liverworts are small, primitive, non-vascular plants. They lack the conductive tissue most plants use to transport water and nutrients. Instead, moisture is absorbed directly into cells by osmosis.
Detailed explanation-5: -Nonvascular plants are a classification of plants that lack a vascular system, specifically the xylem and phloem that transport nutrients and water to the plant. Some algae, including green algae, are considered nonvascular.
