Carbonydrates
Sugar molecules do not diffuse through a plant cell membrane because they are too large and polar to pass through the hydrophobic interior of the lipid bilayer. Instead, sugar molecules are transported across the membrane by specific transport proteins, such as sugar transporters, that facilitate their movement into the cell.
Carbohydrates are the organic molecules composed of monosaccharide monomers. Monosaccharides are single sugar units that can be linked together to form larger carbohydrate molecules such as disaccharides (two monosaccharides linked together) and polysaccharides (long chains of monosaccharides).
Organic compounds made of sugar molecules joined together are called polysaccharides. These polymers play essential roles in storing energy (e.g., starch and glycogen) and providing structural support (e.g., cellulose and chitin) in various organisms.
Organic sugar is made from organic sugarcane or sugar beets that have been grown without the use of synthetic pesticides, herbicides, or fertilizers. Look for the USDA organic certification on the sugar packaging to ensure it is organic.
