One important sugar that are results from photosynthesis is cellulose?

Cellulose is a crucial polysaccharide produced during photosynthesis in plants, where glucose molecules are linked together to form a structural component of the cell wall. Unlike starch, which serves as an energy reserve, cellulose provides rigidity and strength to plant cells, enabling them to maintain their shape and resist external pressures. This complex carbohydrate is also a significant source of dietary fiber for humans and plays a vital role in the ecosystem as it is a primary component of plant biomass.
