how is xylem able to transport water from the roots to the top of even a very tall tree
Answers
Answer:
In a coastal redwood, though, the xylem is mostly made up of tracheids that move water slowly to the top of the tree. STOMATA. These pores in leaves allow water to escape and evaporate--a process that helps to pull more water up through the tree from its roots.
Answer:
Xylem is able to transport water from the roots to the top of the plant maintaining a column of water in small hollow tubes using root pressure, capillary action and the cohesive force of water. Here, Root pressure can be defined as a force or the hydrostatic pressure generated in the roots that help drive fluids and other ions out of the soil up into the plant's vascular tissue which is xylem. Capillary action is basically the forces of cohesion, adhesion, and surface tension. And the cohesion of water is the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another. Thus in conclusion they form stronger and the force used is relatively larger.
