What causes water to move upward through plants?

Answer 1

Transpiration pull through the xylem. Root pressure and osmosis.

A common misconception is that water moves in plants by capillary action, the movement of water along a small-diameter conduit (such as a capillary) as a result of surface tension in the meniscus at the leading surface of the moving water. Surface tension does play a critical role in water movement in plants, as described above, but the relevant surface occurs at the site of evaporation within leaves, not within the xylem conduits, and that surface does not typically proceed along any conduit. Water movement within the xylem conduits is driven by a pressure gradient, not by capillary action.

The xylem transports sap from the root up the plant. Xylem sap consists mainly of water and inorganic ions, although it can contain a number of organic chemicals as well.

Answer 2

Capillary action, in a thin tube surface tension will cause water to move up a tube, but active transport and evaporative draw also have a part in this process.

Answer 3

whilst water evaporates from the exterior of a cellular, rigidity is created, pulling water molecules up in direction of that floor. because of cohesiveness of water molecules, this rigidity is transferred the completed way down the xylem, effectively pulling water to the right of the plant.

Answer 4

During photosynthesis, the plant needs energy to make its own food, so first it needs water. It absorbs the water into its roots to get more energy.

Answer 5

evaporation of the leaves creates a vacuum and lifts the water up the stem.

Look up osmosis

Answer 6

movement of water is enabled by ascent of sap, tugor pressure, osmosis, diffusion.
