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: -They lack true roots, stems, or leaves. They are called non-vascular plants because of the absence of vascular tissues (xylem and phloem) that functions for the conduction of food, water, and minerals.

Detailed explanation-5: -Crytogams are seedless and flowerless plants, reproductive organs are inconspicuous and they reproduce by producing spores. Thallophyta and Bryophyta are correctly termed as non-vascular cryptogams.
