What is the similarities between a monosaccharide and polysaccharide?

Both monosaccharides and polysaccharides are types of carbohydrates. They consist of carbon, hydrogen, and oxygen atoms, typically in a 1:2:1 ratio for monosaccharides. Additionally, both serve as energy sources for living organisms, with monosaccharides providing immediate energy and polysaccharides serving as energy storage or structural components. Both can also participate in biochemical processes, such as glycolysis and cellular respiration.
