How does the water needed to carry out photosynthesis get to leaves

The plants absorb the water from the soil by the roots and then rise (by capillarity) from the stem to the leaves to carry out the photosynthesis.

The amount of water retained by the soil tank, available to the plant, depends essentially on two factors:

* The nature of the soil, in particular its grain size (texture) and the way soil components are organized together (structure).

* The volume of soil prospected by the roots, which depends on the cultivated species and allows a deep and pivoting or superficial and branched rooting.

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
