Explanation

Cell wall presents outside the plasma membranes to protect the cells. It is only present in plants bacteria. It is The cell wall is As made up of cellulose, it gives support and flexibility to cells. In bacteria, it plays an important role to protect it from the external stress and gives specific shape.

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
