AP BIOLOGY

Detailed explanation-1: -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-2: -Mosses are non-vascular plants with about 12, 000 species classified in the Bryophyta. Unlike vascular plants, mosses lack xylem and absorb water and nutrients mainly through their leaves.

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

Detailed explanation-4: -Nonvascular seedless plants, also known as bryophytes, are classified into three phyla: mosses, hornworts, and the liverworts. Nonvascular plants lack seeds and vascular tissue. These plants are very short because they cannot move nutrients and water up a stem.
