List any 6 differences between Xylem and Phloem???
Phloem and xylem are complex tissues that perform transportation of food and water in a plant. They are the vascular tissues of the plant and together form vascular bundles. They work together as a unit to bring about effective transportation of food, nutrients, minerals and water.
|Function:||Transportation of food and nutrients from leaves to storage organs and growing parts of plant.||Water and mineral transport from roots to aerial parts of the plant.|
|Movement:||Bidirectional (Moves up or down the plant 's stem from "source to sink")||Unidirectional (Moves up the plant 's stem)|
|Occurrence:||Roots, stems and leaves||Roots, stems and leaves|
|Additional Functions:||Forms vascular bundles with xylem||Forms vascular bundles with phloem and gives mechanical strength to plant due to presence of lignified cells.|
|Structure:||Tubular with soft walled cells||Tubular with hard walled cells|
|Elements:||Sieve tubes, companion cells, phloem parenchyma, bast fibers, intermediary cells||Tracheids, vessel elements, xylem parenchyma, xylem sclerenchyma|
|Nature of tissue:||Living tissue||Non living tissue at maturity|
