vascular tissue

n

(Life Sciences & Allied Applications / Botany) tissue of higher plants consisting mainly of xylem and phloem and occurring as a continuous system throughout the plant: it conducts water, mineral salts, and synthesized food substances and provides mechanical support Also called conducting tissue

vascular tissue

The tissue in vascular plants that circulates fluid and nutrients. There are two kinds of vascular tissue: xylem, which conducts water and nutrients up from the roots, and phloem, which distributes food from the leaves to other parts of the plant. Vascular tissue can be primary (growing from the apical meristem and elongating the plant body) or secondary (growing from the cambium and increasing stem girth). Seedless plants, and nearly all monocotyledons and herbaceous eudicotyledons, have only primary vascular tissue. The evolution of vascular tissue, especially xylem with its rigid water-conducting cells known as tracheids, provided the plant stem with greater support and allowed plants to grow upright to great heights.

1.

vascular tissue - tissue that conducts water and nutrients through the plant body in higher plants vascular system - the vessels and tissue that carry or circulate fluids such as blood or lymph or sap through the body of an animal or plant tracheophyte, vascular plant - green plant having a vascular system: ferns, gymnosperms, angiosperms plant tissue - the tissue of a plant stele - the usually cylindrical central vascular portion of the axis of a vascular plant cambium - a formative one-cell layer of tissue between xylem and phloem in most vascular plants that is responsible for secondary growth fibrovascular bundle, vascular bundle, vascular strand - a unit strand of the vascular system in stems and leaves of higher plants consisting essentially of xylem and phloem medullary ray, vascular ray - a sheet of vascular tissue separating the vascular bundles xylem - the woody part of plants: the supporting and water-conducting tissue, consisting primarily of tracheids and vessels tracheid - long tubular cell peculiar to xylem phloem, bast - (botany) tissue that conducts synthesized food substances (e.g., from leaves) to parts where needed; consists primarily of sieve tubes sieve tube - tube formed by cells joined end-to-end through which nutrients flow in flowering plants and brown algae
