To "call it a day" means to end an activity or stop doing something because you are tired or have done/had enough. It's a casual expression that is used here to describe how people might not think too deeply into the meaning of apples or apple trees. Ex: Wow, we biked for four hours! Let's call it a day. Ex: The director called it a day after a full day of rehearsals.
