DENDROLOGY

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: -Nonvascular plants are calle d 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-3: -Characteristics of Nonvascular Plants They not only lack vascular tissues; they also lack true leaves, seeds, and flowers. Instead of roots, they have hair-like rhizoids to anchor them to the ground and to absorb water and minerals (see Figure below).

Detailed explanation-4: -Nonvascular seedless plants, as their name implies, lack vascular tissue. Vascular tissue is specialized tissue that transports water, nutrients, and food in plants. As they lack vascular tissue, they also do not have true roots, stems, or leaves.
