Monosaccharides and Photosynthesis Concepts

The video explains photosynthesis, highlighting its role in converting carbon dioxide and water into oxygen and sugars. It delves into glucose, a key monosaccharide, and its importance in energy storage. The video also covers other monosaccharides like fructose and galactose, and introduces disaccharides and polysaccharides. It concludes with the properties and classifications of monosaccharides.
