- #42 Summary Of Transport In Multicellular Plants
1. Multicellular organisms with small surface area to volume ratios need transport systems. 2. Water and mineral salts are transported through a plant in xylem vessels. Movement of water is a passive process in which the water moves down a water...
- #41 Transport In Phloem
The movement of substances in phloem tissue is called translocation. The main substances that are moved are sucrose and amino acids, which are in solution in water. These substances have been made by the plant and are called assimilates. Phloem...

Phloem & Xylem
Are Phloem and Xylem Similar? What are the Differences?
Similarities: Phloem and xylem are tissues in a plant that transport food and water. Both are vascular tissues and when they work together to effectively transport food, water and minerals they form a vascular bundle. They each have a tubular shape and are in the roots, stems and leaves of the plant.
Differences:
phloem
- transports nutrition to storage and growing parts of plant
- has soft wall cells
- bidirectional, meaning moves up OR down plants stem
- elements; companion cells, bast fibers, intermediary cells, sieve tubes
- living tissue
xylem
- transports nutrition to aerial parts of plant
- has hard walled cells
- unidirectional, moves only up the stem
- elements; tracheids, vessels, xylem parenchyma
- NON living tissue
- gives mechanical strength to plant because of lignified cells
