yes, water is pulled from the ground roots through adhesion. whihc is the water molecules bonding together

The way I picture this occurring is envisioning a long chain of water molecules continuous from the roots up through the stems continuing to the leaves. As water is pulled from the plant through transpiration
and used by the plant in photosynthesis, the 'chain' is pulled upwards. This pulls molecules upwards through the stem; molecules enter the roots to replace those 'pulled' out of the stem into the leaves. You can picture what happens to a plant on a dry day when there is no water in the ground for the roots to absorb: water lost by photosynthesis and through transpiration cannot be replaced by water entering the roots, and the plant begins to wilt. As more and more water is lost, the wilting worsens. The plant uses water pressure to close its stomata which are essentially pores on the leaves' surfaces (usually undersides). This can reduce water loss somewhat. If water is not provided to the plant for root uptake, the roots can begin to die.
Loss of root mass causes further problems as now even LESS water can be absorbed into the plant. Part of the upper part of the plant may die back--the severity of this is usually dictated by the amount of root mortality.

Roots absorb water and minerals that the plant needs to grown. The roots store food for later use as it grows.

Plants pull the water up into them, yes...water is absorbed via the roots and is distributed throughout the plant.

Yes, because water is a polar molecule (one end is positive and the other is negative). That means water molecules attract one another and pull each other up the root. That's called cohesion... but you didn't ask for an essay, so I'll leave it at that. (^_^)

water is absorded up by the roots

yes it is called osmosis. just like it will travel up a piece of toilet paper.
