Detailed explanation-1: -Nonvascular plants, which include mosses, liverworts, and hornworts, lack a system for delivering nutrients inside their bodies. Vascular tissue is made up of vessels known as xylem and phloem.

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: -Mosses and liverworts are small, primitive, non-vascular plants. They lack the conductive tissue most plants use to transport water and nutrients. Instead, moisture is absorbed directly into cells by osmosis.

Detailed explanation-4: -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.
