Detailed explanation-1: -Mosses, hornworts, and liverworts are nonvascular plants called Bryophytes. There are an estimated 17, 000 species of bryophytes and occupy almost every habitat type.

Detailed explanation-2: -Mosses, liverworts and hornworts are collectively called “bryophytes.” Bryophytes are nonvascular plants: They do not have special tissues-tissues that botanists call “xylem” and “phloem”-to transport fluids and nutrients internally. Additionally, bryophytes do not produce flowers and seeds.

Detailed explanation-3: -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-4: -The xylem of gymnosperms is devoid of vessels.
