vascular bundle of typical leafs of angiosperm
Answers
vascular bundle (fascicle) A long continuous strand of conducting (vascular) tissue in tracheophyte plants that extends from the roots through the stem and into the leaves. It consists of xylem and phloem, which are separated by a cambium in plants that undergo secondary thickening. See vascular tissue.
Answer:
Organization of the vascular tissue
Vascular tissue is organized into discrete strands called vascular bundles, each containing xylem and phloem. In stems, the vascular tissue is organized into many discrete vascular bundles. In the roots, the vascular tissue is organized within a single central vascular cylinder. The anatomy of roots and stems is discussed in their respective sections below.The xylem conducts water and minerals within the primary plant body, and the phloem conducts food. The xylem cells are arranged end to end to form a longitudinal continuum throughout the plant. The phloem cells form a similar continuum. Thus, water enters the xylem cells in the roots and travels to the leaves via the stems, and photosynthates (products of photosynthesis) enter the phloem cells in the leaves and are translocated to the roots via the stems. Storage parenchyma and fibres are generally present, and sclereids rarely are.
