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. Bryophytes include liverworts, hornworts and mosses.

Detailed explanation-2: -Vascular plants: a plant that has tubes that carry water, nutrients, and food to different parts of the plant. 3. Nonvascular plant: a plant that does not have tubes.

Detailed explanation-3: -Non-vascular plants are plants without a vascular system consisting of xylem and phloem. Instead, they may possess simpler tissues that have specialized functions for the internal transport of water.

Detailed explanation-4: -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-5: -noun. : a simple, low-growing, nonflowering plant (such as a moss or liverwort) that lacks specialized conducting channels for transporting water and nutrients and in which the photosynthetic gametophyte is the dominant stage of the life cycle.
