The four main groups of macromolecules are carbohydrates, lipids, proteins. Identify each type of macromolecule based on its monomer.

1) GLUCOSE is the monomer for CARBOHYDRATES

2) FATTY ACID & GLYCEROL is the monomer for LIPIDS

3) NUCLEOTIDE is the monomer for  NUCLEIC ACIDS

4) AMINO ACID is the monomer for PROTEINS

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.
