Detailed explanation-1: -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-2: -Credit: José Gudiño, STRI. What are bryophytes? 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).

Detailed explanation-3: -Summary. Nonvascular plants are calle d bryophytes. Nonvascular plants include liverworts, hornworts, and mosses.

Detailed explanation-4: -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.

Detailed explanation-5: -Nonvascular plants have a dominant gametophyte phase, but vascular seedless plants have a dominant sporophyte phase.
