Nevertheless accurate observation has shown that where starch is formed, either leukoplasts or chloroplasts are constantly present, and precede them. It thus appears that the capacity for converting sugar into starch resides in the plastids. But when the insoluble starch is again required for physiological use, it is converted back into sugar, in which form it can be transferred to the point where it is required.
