All rice is composed of two types of starch--dry and sticky. The dry starch, amylose, is higher in long-grain (indica) rice and, when cooked, produces drier rice with separate grains. The sticky starch, amylopectin, is higher in short-grain (japonica) rice and, when cooked, produces soft rice with clinging grains. Long-grain varieties are four to five times longer than wide.
