IPA: /ˈeɪ.mɪ.lə.plæst/
KK: /ˈæmɪləˌplæst/
A type of cell structure in plants that is responsible for producing and storing starch granules.
Amyloplasts are found in potato cells, where they store starch for energy.
Amyloplast is formed from "amylum" (from Greek "amylon", meaning starch) and "-plast" (from Greek "plastos", meaning formed or molded). An amyloplast is a type of organelle in plant cells that is specifically involved in the storage of starch, thus relating to its roots in starch formation.
Think of 'starch' ('amylum') being 'formed' ('-plast') in plant cells — that's what an amyloplast does.
