Storage. As opposed to RAM
In animals, they are primarily energy storage molecules, although there are a lot of polysaccharide chains that do many extremely important jobs on the membranes of body cells. In plants, they are not only very important food storage molecules (starch), they also serve as structural materials (cellulose) and components in wood.
No, they are simple storage molecules.
Starch or TAGs
There are 2 types of vascular tissue in plants: xylem & phloem. Xylem is a structurally & functionally complex tissue concerned primarily with water conduction, storage & support. Phloem tissue is also both structurally & functionally complex. Phloem is concerned with the distribution of primarily organic molecules between "sources", that is, photosynthetic or storage tissues, and "sinks", or regions of active growth & metabolism.
Storage molecules, transport molecules, and movement.
They function as storage molecules as well as structural molecules. For example: storage- glycogen structural- chitin (hard exoskeleton of ants and other insects)
Cells use lipid molecules for energy storage as well as insulation and structuring. These molecules are mostly known in the vernacular as fats although they do encompass more than just traditional fat molecules.
Estrogen causes fat storage to be primarily in the hips and buttocks. Men, who lack estrogen, primarily story mesenteric(lower abdominal) fat.
