Xylem and phloem are known as complex tissues as they are made up of more than one type of cells. These cells work in a coordinated manner, as a unit, to perform the various functions of the xylem and phloem. Xylem helps in conducting water and minerals. It also provides mechanical suppo...

Xylem and phloem are two distinct vascular tissues found in plants. Xylem primarily transports water and minerals from the roots to the rest of the plant, while phloem primarily carries sugars and other organic compounds produced through photosynthesis. Xylem consists of dead cells and operates throug...
The growth of secondary xylem and phloem depends on the division of cells in the vascular cambium and results in an increase in the diameter of the root and stem. Very little is known about the genetic mechanisms that control cambial activity and the differentiation of secondary xylem and phloem...
This chapter focuses on the long-distance transport of solutes in the xylem and phloem, which plays important roles in shoot nutrition, redistribution of essential elements between tissues during ontogeny, maintenance of charge balance in leaves of nitrate-fed plants, removal of potentially toxic eleme...

The plant vascular system is composed of two tissue types, xylem and phloem, which originate from the vascular meristem, the procambium. Recently, several regulatory mechanisms that control the specification of these two tissue types have been uncovered. These include the asymmetric patterning of xyle...
Phloem and xylem cells differentiate continuously throughout the period of seed development. The mature xylem consists of tracheary elements with helical secondary wall thickenings. The mature phloem consists of sieve elements and adjoining companion cells. The sieve elements did not form P-protein ...
