AP BIOLOGY

Detailed explanation-1: -Vascular plants are known as tracheophytes. Vascular tissues include xylem and phloem. They allow plants to grow tall in the air without drying out. Vascular plants also have roots, stems, and leaves.

Detailed explanation-2: -Ferns are vascular plants Ferns and other vascular plants can grow much taller than nonvascular plants. Being tall is only possible for plants with a highly developed vascular system for transporting materials between the roots and the shoot, which is the part of the plant above the ground.

Detailed explanation-3: -Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.

Detailed explanation-4: -Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants). Scientific names for the group include Tracheophyta, Tracheobionta and Equisetopsida sensu lato.

Detailed explanation-5: -Primary Xylem It allows the plant to grow taller and the roots to grow longer. This growth is called primary because it occurs first in the growing season, before secondary growth. Both primary and secondary xylem transport water and nutrients.
