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...
Intra-annual density fluctuations indicate shortterm events during the growing season. They mainly occur in the xylem of perennial plants in temperate, arid and tropical climates and are virtually absent in cold climates.Springer Berlin Heidelberg...
Vascular tissue:Vascular tissueis a complex conducting tissue, formed of more than one cell type, found in vascular plants. 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 ...
Briefly explain the function of the xylem and phloem. What is the function of xylem tissue in plants? Describe similarities and differences between xylem and phloem. What is the function of the xylem tissue in a plant? Explain the function of the xylem as one of the vascular bundles....
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...
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...

What is the main difference between a vessel and a vein? A vessel is any tubular structure carrying blood or lymph, whereas a vein is a specific type of blood vessel that returns deoxygenated blood to the heart. 7 What is the significance of pulmonary veins? Pulmonary veins are unique as ...
The electrolyte leakage, as measured in the REL method, is an integrated measure of damage in different tissues, i.e. in the phloem, cambium, and xylem. It is not an ON/OFF phenomenon, similar to the LTE, which originates from the xylem ray parenchyma cells in species with a ring-...
The radial solute exchange between xylem and phloem is an important determinant of the natrient distribution and C/N economy of seed plants. Nevertheless, our knowledge of the mechanism of xylem—phloem exchange is very limited. This paper aims to integrate anatomical and physiological data about ...
