Answer 1

macro = large
Molecules = simplest form of compounds :P

Answer 2

Macro molecules are the molecules which are the aggregate of small molecules. They possess high molecular mass.

Answer 3

"There are four classes of macromolecules that constitute all living matter: carbohydrates, lipids, proteins, and nucleic acids. While they have different structures and functions, they are all composed of long complex chains of molecules (polymers) made up of simpler, smaller subunits (monomers). They are joined together in a process known as dehydration synthesis, in which a covalent bond is formed between two monomers by releasing a water molecule. "

Answer 4

A macromolecular substance is a giant covalent structure such as SiO2 (Silicon Dioxide). It is a single molecule that is very large.
