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.
What type of vascular tissue carries water and minerals from roots to the stem and leaves?
Xylem tissue is responsible for transporting water and minerals from the roots to the stem and leaves of a plant. It consists of specialized cells that form a network of tubes to facilitate the upward flow of water and nutrients.
How do xylem and phloem tissues differ?
Xylem is deeper inside the plant (near the trunk) and transports water up to the leaves. Phloem is near the outside and transports sugar and other materials all throughout the plant.Xylem has a one way flow, while phloem can go either directions.Xylem Is in the roots. Go Apex Kids -Emily
What direction does the xylem transport water?
The xylem in a plant transports water and dissolved minerals from the roots to the shoots and leaves. The movement of water is typically upward and against gravity due to the cohesion and adhesion properties of water molecules within the xylem vessels.
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.

Why does the flow of materials in phloem reverse direction in winter?
can i get some help
Plant that depends on diffusion to move materials?
I assume you are referring to the mass flow hypothesis, where water from the Xylem is diffused into the phloem, adding pressure inside of the phloem which causes the movement of materials through the plant. Any good A-level (erm...or American equivalent?) textbook will have a full description of mass flow hypothesis. I found (a long time ago :( ) when I was learning this that drawing yourself a diagram of it helps a lot. Good luck.
What direction does the xylem transport water?
The xylem in a plant transports water and dissolved minerals from the roots to the shoots and leaves. The movement of water is typically upward and against gravity due to the cohesion and adhesion properties of water molecules within the xylem vessels.
Which process requires more energy from the plant moving water up through the xylem or moving nutrients down through the phloem?
Moving water up through the xylem requires more energy from the plant compared to moving nutrients down through the phloem. This is because water movement in the xylem involves overcoming gravity and transpiration, which requires energy to pull water from the roots to the leaves. Nutrient movement in the phloem, on the other hand, occurs through pressure flow and does not require as much energy expenditure from 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.
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.
Carries nutrients to the leaves and other parts of the plant?
The vascular system of a plant, composed of xylem and phloem, is responsible for transporting water, nutrients, and sugars throughout the plant. Xylem carries water and minerals from the roots to the leaves, while phloem transports sugars produced in the leaves to other parts of the plant for growth and energy. This continuous flow of nutrients is essential for the plant's overall health and function.
