StructureMultiple cross sections of a stem showing phloem and companion cells[1]
Phloem tissue consists of less specialized and nucleate parenchyma cells, sieve-tube cells, and companion cells (in addition albuminous cells, fibers and sclereids).
Sieve tubesThe sieve-tube cells lack a nucleus, have very few vacuoles, but contain other organelles such as ribosomes. The endoplasmic reticulum is concentrated at the lateral walls. Sieve-tube members are joined end to end to form a tube that conducts food materials throughout the plant. The end walls of these cells have many small pores and are called sieve plates and have enlarged plasmodesmata.
Companion cellsThe survival of sieve-tube members depends on a close association with the companion cells. All of the cellular functions of a sieve-tube element are carried out by the (much smaller) companion cell, a typical plant cell, except the companion cell usually has a larger number of ribosomes and mitochondria. This is because the companion cell is more metabollically active than a 'typical' plant cell. The cytoplasm of a companion cell is connected to the sieve-tube element by plasmodesmata.
There are three types of companion cell.
The first two types of cell collect solutes through apoplastic (cell wall) transfers, whilst the third type can collect solutes symplastically through the plasmodesmata connections.
In vascular plants, xylem is one of the two types of transport tissue, phloem being the other. The word "xylem" is derived from classical Greek ξυλον (xylon), "wood", and indeed the best known xylem tissue is wood, though it is found throughout the plant. Its basic function is to transport water.
Physiology of xylemThe xylem is responsible for the transport of water and soluble mineral nutrients from the roots throughout the plant. It is also used to replace water lost during transpiration and photosynthesis. Xylem sap consists mainly of water and inorganic ions, although it can contain a number of organic chemicals as well. This transport is not powered by energy spent by the tracheary elements themselves, which are dead at maturity and no longer have living contents. Two phenomena cause xylem sap to flow:
Xylem can be found:
Note that, in transitional stages of plants with secondary growth, the first two categories are not mutually exclusive, although usually a vascular bundle will contain primary xylem only.
The most distinctive cells found in xylem are the tracheary elements: tracheids and vessel elements. However, the xylem is a complex tissue of plants, which means that it includes more than one type of cell. In fact, xylem contains other kinds of cells, such as parenchyma, in addition to those that serve to transport water.
Primary and secondary xylemPrimary xylem is the xylem that is formed during primary growth from procambium. It includes protoxylem and metaxylem. Metaxylem develops after the protoxylem but before secondary xylem. It is distinguished by wider vessels and tracheids.
Secondary xylem is the xylem that is formed during secondary growth from vascular cambium. Although secondary xylem is also found in members of the "gymnosperm" groups Gnetophyta and Ginkgophyta and to a lesser extent in members of the Cycadophyta, the two main groups in which secondary xylem can be found are:

The End
The process is called transpiration. Water is absorbed by a tree's roots and then transported through the plant and released as vapor through small pores on the underside of the leaves called stomata.
Water and minerals are transported from the roots to the leaves through the xylem tissue in plants. This process is called transpiration and helps provide essential nutrients and support for the plant's growth and development.
Evaporation from the leaves is called transpiration.
It could evaporate from anywhere! The stems, branches, and leaves have probably the most moisture. Usually water doesn't evaporate directly from a tree- the tree 'sweats'. This phenomenon is called perspiration.
Water is absorbed by the plant's roots from the soil and transported through the stem to the leaves via specialized tissues called xylem. This process, known as transpiration, helps supply water and nutrients to the leaves for photosynthesis and other metabolic processes.
No, a tree's branches do not deliver nutrients from the soil to the leaves. Instead, nutrients are absorbed by the tree's roots from the soil and transported through the xylem tissue in the trunk and branches to the leaves. The leaves then use these nutrients, along with water and sunlight, to perform photosynthesis and produce energy for the tree.

It Makes Water From The Leaves
in the leaves
Tree roots have extensive surface areas and hairs to absorb water and nutrients efficiently from the soil, while the leaves have a large surface area with stomata for gas exchange and photosynthesis to produce sugars. This allows roots to take up water and nutrients and transport them to the leaves, where sugars are synthesized and transported to other parts of the tree for growth and energy.
Water is absorbed by plant roots and transported, by capillary action, through the fibrous material of the plant stem, to the leaves.
answer is the vascular system
Water and nutrients are transported to the leaves by the xylem tissue in plants. These essential substances are absorbed by the roots and then move upward through the plant's vascular system to reach the leaves where photosynthesis occurs.
A tree's roots have a large surface area covered in tiny root hairs that can absorb water and nutrients efficiently from the soil. The leaves, through tiny pores called stomata, can take in carbon dioxide from the air for photosynthesis, producing sugars that are then transported throughout the tree for energy and growth. This separation of functions allows roots to focus on water absorption and leaves to specialize in sugar production, optimizing the tree's overall health and growth.
The tree takes up water and minerals from the soil, which are essential for photosynthesis to occur. Water and minerals are absorbed through the tree's roots and transported to the leaves where photosynthesis takes place.
The roots of a tree absorb water from the soil and transport it up through the trunk to the leaves via the xylem tissue. This water is essential for the tree's growth, photosynthesis, and overall health.
