WebbPlants have transport systems to move food, water and minerals around. These systems use continuous tubes called xylem and phloem: - Phloem tubes carry sugar & other organic nutrients made by plant from the leaves to the rest of the plant. Xylem vessels consist of dead cells. They have a thick, strengthened cellulose cell wall with a hollow lumen. WebbThe main function of phloem is to transport assimilates to sinks via translocation. Phloem contains four specialised cell types: sieve tube elements, companion cells, phloem fibres …
Webb3 feb. 2024 · Xylem is the dead, permanent tissue that carries water and minerals from roots to all other parts of the plant. The term ‘xylem’ is derived from the Greek word ‘xylon’, meaning wood. Phloem, on the other hand, is the living, permanent tissue that carries food and other organic nutrients from leaves to all other parts of the plant.

WebbSieve elements are specialized cells that function in the conduction of sugars. They are typically associated with parenchyma and often some sclerenchyma in a common tissue known as phloem (Gr. phloe, bark, after the location of secondary phloem in the inner bark).Sieve elements are elongate cells having only a primary (1°) wall with no lignified …

Unlike xylem (which is composed primarily of dead cells), the phloem is composed of still-living cells that transport sap. The sap is a water-based solution, but rich in sugars made by the photosynthetic areas. ...

It carries the photoassimilates from the site of photosynthesis (leaves) to the non-photosynthetic parts of the plants (stems and roots). The food it carries is termed as phloem sap. children\\u0027s lexingtonWebbPhloem 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.
