<span>The main light-absorbing pigment for photosynthesis is known as chlorophyll. This light absorbing pigment is found in many organisms, primarily in a variety of plant and bacteria species. Chlorophyll is necessary because it allows the light to be absorbed and allow energy to be absorbed by the organism in order to carry out a multitude of metabolic processes.</span>
Lipids are macromolecules which provide insulation.
<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.
