Which statement describes how water is pulled up through the xylem to the leaves of the plant? As water exits the leaf, hydrogen bonding between water molecules pulls more water up from below. A As water exits the leaf, signals are sent to the roots to pump more water up to the leaves through the xylem by adhesion. B Evaporation from the leaf decreases the hydrogen bonds that form between the water molecules in the xylem, which helps the water molecules to be pulled up the xylem. C Evaporation of water from the leaf increases the hydrogen bonds that form between water molecules in the air, providing the energy for transport.

Respuesta :

Option (A) is Right Answer

Explanation:

    A As water exits the leaf, signals are sent to the roots to pump more water up to the leaves through the xylem by adhesion

  • Water diffuse out of the stomata, this makes pressure in the xylem
  • Water is therefore pulled upwards as it replaces the water that is lost
  • It goes in a ceaseless "line" up the xylem because of the attachment inside water, this importance the hydrogen bonds that structure between each water molecule Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by dispersion through the stomata

Xylem is a system by which water is pulled through the xylem to the leaves of the plant, Evaporation from the leaf decreases the hydrogen bonds that form between the water molecules in the xylem, which helps the water molecules to be pulled up the xylem, to understand better about how xylem works we need to know that.....

Transport in the xylem

When water evaporates into the atmosphere, the formation of a remaining surface of water occurs, which migrates to the interstices of the cell wall, where curved air-water interfaces are formed. This curvature leads to a negative pressure on the water, and the more water is evaporated, the more this curvature increases, also increasing this pressure, generating the driving force of water transport in the xylem.

With this information, we conclude that alternative B is the correct one.

  • B) Evaporation from the leaf decreases the hydrogen bonds that form between the water molecules in the xylem, which helps the water molecules to be pulled up the xylem.

Xylem is an important factor for the survival of large trees, and this mechanism supports life.
