What is the purpose of the xylem and phloem?
The xylem transports water and nutrients from the roots to the rest of the plant.
the phloem transports sucrose (sugars) throughout the plant
Xylem is different from phloem structurally and functionally. Xylem consists of Tracheids, vessels and xylem parenchyma whereas phloem consists of Sieve tubes, companion cells and phloem parenchyma. Xylem conducts water and minerals to the leaves whereas phloem transports the prepared food from leaves to different parts of plant body.
Dicot Plants: Root - adradial arrangement = Xylem makes a cross in the centre, phloem is in the corners of the cross. No pith. Stem - Perradial arrangement = Xylem and phloem in the same vascular bundles. Bundles arranged in a circle around the stem. Have a Caspian strip in between xylem and phloem. Xylem closer to the middle Monocot: Root - randomly placed xylem and phloem surrounding the pith Stem - Random bundles of…
Phloem cells differ from xylem cells in a tree structurally and functionally. The phloem consists of sieve tubes, companion cells and phloem parenchyma, whereas, the xylem consists of Vessels, tracheids and xylem parenchyma. Xylem functions in transporting water and minerals from roots to the leaves whereas phloem transports prepared food material from leaves to various parts of the plant.
