How does sugarcane make sucrose? [Full subscriber]

Photosynthesis is a complex process by which carbon dioxide, water and inorganic salts are converted into carbohydrates by green plants, using chlorophyll and energy from the sun. Generally these carbohydrates are stored as starch and cellulose in plant roots, young shoots and developing seeds. Sugarcane has the important ability to store sucrose directly in stalk cells. These cells are alive and adaptable to various functions such as photosynthesis, secretion and food storage. The sugarcane stalk can therefore supply sucrose directly to humans (Accessed 13th Aug). Plants need an energy source to grow. In growing plants, sugars produced by photosynthesis in leaves are transported…
