What is the method trees use to bring water up from their roots?

Answer 1

The roots have tiny little hairs on them and the groundwater is sucked in the roots through osmosis and then transported through the tree from there.

Answer 2

The roots draw water into the plant by OSMOSIS, the movement of water through a semi permenant membrane, from high conc
: to low conc: the water moves through either of 2 pathways to the Xylem of the stem and up the stem to all parts. The leaves have stomata which when open release water. It is the pull of the water removed by the stomata and the intake of water by the roots which move the water around the plant.I am presuming that you have access to a good biological text book and can look up the following term.1 Osmosis. 2. Turgor pressure. 3. Vascular bundles. 4. Phlom, Xylem and Cambium 5. Stomata and guard cells. 6. Secondary thickening 7. Adaptions to drought. 8. Plasdesmata of cells. I hope this has given you some ideas of where to look. The actual description of the movement of water through a plant is very long winded and has taken several pages to describe even by the best writers.

Answer 3

The largest single use of water in a tree is for
transport of essential materials from roots to leaves. This transport is called the “transpiration stream”
and occurs in columns of dead xylem cells within the last few annual rings of the tree. Living cells surrounding this xylem lift system assist with monitoring the water stream. Clearly, water is critical to this basic process.
Pulling Bonds
Because of water’s chemical properties, and their modification when materials are dissolved or suspended, water sticks together and adheres to various surfaces. Water has an affinity for sticking closely to other water molecules. This property is why drops of water placed on a wax (hydrophobic)
surface bead-up rather than flattening out and covering the surface. In this case, water would rather stick to other water molecules than to the wax surface. Using your finger, you can “pull” water droplets over the waxy surface and consolidate them into larger drops. Trees utilize water’s special chemical features in many ways, most noticeably in transporting
materials into the root and then on to the leaf. Water is pulled in long chains into the root, up through narrow xylem columns or channels, and to the leaf surface where it evaporates into the perpetually dry air. Water evaporates as bonds between molecules are broken by energy concentrated at the liquid water
surface.

Answer 4

John: Plants take up water by osmosis through mostly the root hairs. The water then flows from cell to cell through the plasmadesmata (tiny interconnections between adjacent cells). Water cannot enter the plant around root cells due to the presence of the Caspian strip which is hydrophobic (repels water) that restricts water movement into the inner cells of the root so that only clean water flowing through cells moves to the xylem. Finally, water enters the xylem where capillary forces, aided by the water properties of adhesion (stickiness to the xylem walls) and cohesion (self association), allow it to move up the plant driven also by transpiration (loss of water from the leaves). Plants can, in this way, get water up long distances.

The soda-straw model does not explain tall tree water relations since the highest distance you can raise water by suction alone would be 33.9 feet [divide the atmospheric pressure at see level, 14.7 lbs/sq in, by the weight of one cubic inch of water, 0.0361 lbs = 407.2", or 33.9 ft]. As a nice trip to the redwood forests in California will confirm, plants grow well over this height!

Answer 5

As water evaporates from the leaves, cohesion between water molecules pulls water up the tree, much in the same way as when you suck water through a straw, more water follows it up.
