Detailed explanation-1: -They do not produce flowers, fruits and seeds.

Detailed explanation-2: -Globally there are around 11, 000 moss species, 7, 000 liverworts and 220 hornworts. As they are not flowering plants, bryophytes reproduce by spores instead of seeds. “They can produce thousands or millions of spores, and they disperse them using the wind as their vector, ” Villarreal says.

Detailed explanation-3: -Nonvascular plants are called bryophytes. Nonvascular plants include liverworts, hornworts, and mosses. They lack roots, stems, and leaves.

Detailed explanation-4: -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.
