What direction does the xylem transport water?
The flow is from the roots to the plant so the flow goes up.
How is phloem transport different from xylem transport?
Phloem has a two-way flow
How is a phloem cell specialised?
Xylem vessels are made up of dead cells with a thick, strong cell walls and have a hollow lumen that allows water to flow through them. The xylem cells form continuous tubes from the leaves down to the roots. This acts like a drinking straw and helps in the flow of water with dissolved minerals from the roots to the leaves.
Contrast the flow of materials in xylem and phloem?
Both are vascular tissues of the vascular plant. Xylem is dead, woody tissue mostly that transports water from the roots of the plant to the leaves. Phloem is vascular tissue that transports sugars manufactured by the plant to all the areas that need such sugars.
In a plant the pressure flow hypothesis explains the movement of sugar from the to the?
The movement of sugars in the phloem begins at the source, where (a) sugars are loaded (actively transported) into a sieve tube. Loading of the phloem sets up a water potential gradient that facilitates the movement of water into the dense phloem sap from the neighboring xylem (b). As hydrostatic pressure in the phloem sieve tube increases, pressure flow begins (c), and the sap moves through the phloem by mass flow. Meanwhile, at the sink (d), incoming sugars are actively transported out of the phloem and removed as complex carbohydrates. The loss of solute produces a high water potential in the phloem, and water passes out (e), returning eventually to the xylem.

The flow is from the roots to the plant so the flow goes up.
How is pholem different from xylem?
Xylem is different from phloem structurally and functionally.Xylem consists of Tracheids, vessels and xylem parenchyma whereas phloem consists of Sieve tubes, companion cells and phloem parenchyma.Xylem conducts water and minerals to the leaves whereas phloem transports the prepared food from leaves to different parts of plant body.

The vascular tissue through witch food moves in some plants?
There are two types of vascular tissue in plants - the xylem and phloemXylem are elongated water conducting cells. The walls of the xylem are perforated and allow water and salts to pass though side ways from cell to cell.The walls of the xylem tissue are strengthened by deposition of lignin on them. This lignin makes the cell woody and impermeable. Xylem is the wood in woody plants that also help in supporting the plants.Phloem are living cells supported by companion cells. The end walls of these calls are perforated and allow organic solutes to flow to different parts of the plant.
Sugars are conducted through plant tissue by the?
The sieve tubes of the phloem cells help to transport sugars. The stem of the plant has a layer of cells called phloem. Part of the phloem is made of sieve tubes that permit the flow of sugars solution through the influence of fluid pressure differential. The phloem also contains companion cells for the sieve tubes which aid in the transport of sugars to these tubes.
Why does the flow of materials in phloem reverse direction in winter?
can i get some help
What is xylem flow in plants?
Xylem transports water throughout the plant.
How do phloem cells differ from xylem cells in a tree?
There is a layer of living Phloem and there is a layer of living xylem. Both these layer produce dead tissue, the Phloem produces bark (dead protective outer layer), the xylem produces wood (dead supportive inner layer). Both the wood and the bark are dead. It is only the two thin layers of Phloem and Xylem that are alive.
Does phloem have a two-way flow?
Yes, this facilitates the distribution of food material to all parts of the plant equally well.
