Detailed explanation-1: -Nonvascular plants (often referred to collectively as the bryophytes) include three groups: the mosses (Bryophyta), approximately 15, 000 species; liverworts (Hepaticophyta), approximately 7500 species; and hornworts (Anthocerophyta), approximately 250 species (Table 1).
Detailed explanation-2: -The plant world is conveniently separated into two major groups: nonvascular plants and vascular plants. The nonvascular plants include the bryophytes, while the vascular plants include the ferns, gymnosperms, and angiosperms (see Chapter 19).
Detailed explanation-3: -Vascular tissue is comprised of the xylem and the phloem, the main transport systems of plants.
Detailed explanation-4: -Vascular plants are plants found on land that have lignified tissues for conducting water and minerals throughout the body of the plant. Non-vascular plants are plants mostly found in damp and moist areas and lack specialized vascular tissues.
