Xylem and phloem: Xylem and phloem are tissues in plants that transport water and solutes up the plant (xylem) and food down the plant (phloem). Flowers: A flower is the part of a plant containing.
WebbPHLOEM. Phloem tissue transports photosynthetic products, other organic molecules (e.g., plant hormones and waste products), and soluble nutrients throughout the plant. Unlike xylem, phloem is alive at maturity, but usually with a much reduced cell contents and no nucleus. This is logical because movement of material through phloem tissue relies on …
WebbPhloem is located between the “prongs” of the xylem. While monocot roots have oval or rounded xylem vessels, dicot roots contain angular or polygonal vessels. Dicot roots usually have 2 to 6 fewer xylem-phloem components than monocot roots (8 or more). Development of Xylem great lakes boat excursionsWebbThe stele (or vascular cylinder) is in the central region of the root, where the xylem and phloem develop. In dicot roots, the stele contains clusters of phloem arranged around the central xylem. Dicot steles contain an additional component, not present in monocot roots, called cambium. Dicot root steles do not contain pith. See it in 3D!
