IPA: /ˈplæstɪdɪəl/
KK: /ˈplæstɪdɪəl/
Relating to a type of cell organelle involved in photosynthesis and other important functions in plant cells.
The plastidial functions of the cell are essential for its energy production.
Plastidial is derived from "plastid" (from Greek "plastos", meaning formed or molded) and the suffix "-ial" (meaning relating to). The term refers to something that is related to or characteristic of plastids, which are organelles involved in the synthesis and storage of food in plant cells.
Think of 'plastos', which means 'formed', to remember that 'plastidial' relates to the formed structures in plant cells.
