Alternate spelling: leukoplast
Etymology: Greek leucos (white) + Greek plasm (anything formed or shaped).
They serve various functions, for example, storage of starch, lipids, or proteins. Plastids of these three types are respectively known as amyloplasts, elaioplasts, and proteinoplasts. A leucoplast may also perform biosynthetic functions such as the synthesis of fatty acids, amino acids, and various other compounds.
Although they vary in shape, a leucoplast is usually much smaller than a chloroplast.
