DENDROLOGY

Detailed explanation-1: -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-2: -Vascular tissue is comprised of the xylem and the phloem, the main transport systems of plants.

Detailed explanation-3: -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.
