amyloplast

am·y·lo·plast

(am'i-lō-plast), A granule in the protoplasm of a plant cell that is the center of a starch-forming process and starch storage. Synonym(s): amylogenic body [amylo- + G. plastos, formed]

amyloplast

a type of cell inclusion found in many plant tissues, particularly storage organs such as the potato tuber. Amyloplasts contain starch enclosed in a UNIT MEMBRANE, the whole structure being a type of LEUCOPLAST. Besides serving as a starch store, amyloplasts are thought by some scientists to function also as a gravity-seeking device, helping the roots to push through the soil in the correct direction (see GEOTROPISM).
