Question

Describe the pathways and forces which enable water to move from the soil to the leaves of tall trees

Answer 1

There are different forces which are responsible for the uptake of water.  Osmosis, cohesion, capillary action of the xylem tissue, transpiration pull take part in the uptake of water from the soil to the leaves of tall trees.

Answer 3

It is called active transport.It is when the soil contain very little water or nutrients,the plant uses the energy to transport the useful nutrients and water from the soil into the plant.when the plants lack a lot of water,the water in the stem will move up the tree as there is a prescence of adhesion and cohesion force between the water particles and the cell wall of the xylem vessel.

Answer 4

The first thing to think about is osmotic potential. What this means is that water wants from areas with a high concentration to areas with low concentrations. Trees have vessels that carry water from their roots to their leaves the same way that we have blood vessels. One key difference is that these vessels in trees are very narrow. As the water in tree leaves is evaporated osmotic potential pulls water up into the leaves due to the low concentration of water. Water is capable of being pulled because it has high cohesion. These means that water molecules want to stick together. Because the vessels are so narrow the force of gravity does not exceed the force of the water cohesion. That means that the water can be pulled up very tall trees. Also many tall trees such as Americas Redwoods (Tallest tree in the world) live in areas with lots of mists or fog and  also absorb water from the  air.
