Referring to the nonliving substances produced by living cells during their activity.
The ergastic substances in the plant cells include starch and oils.
Ergastic is derived from the Greek word "ergastikos" (meaning working or laboring) and the suffix "-ic" (meaning pertaining to). The term refers to substances produced by cells during metabolic processes, thus relating to the concept of work or activity in biological contexts.
Think of 'working' ('ergastikos') to remember that 'ergastic' pertains to substances related to cellular activity.
