DENDROLOGY

Detailed explanation-1: -Vascular plants are also known as tube plants (tracheophytes). The presence of vascular tissues such as xylem (tube-like) and phloem ( tubular cells) plays a role in distributing food and water to the plant cells. Other ordinary characteristics include stems, leaves, and roots that hold the plant and provide support.

Detailed explanation-2: -Plants like ferns and conifers have xylem “straws” that are made of slender cells called tracheids. At maturity these cells die, leaving behind a rigid cell wall scaffolding tube to conduct water and minerals. Flowering plants have an additional type of xylem tissue called a vessel element.

Detailed explanation-3: -Vascular tissue is comprised of the xylem and the phloem, the main transport systems of plants.
