Answer:
The practical lesson of a story; a sentence or passage coming at the end of the story and pointing out the lesson or conclusion to be drawn from the story - is the moral of the story.
Explanation:
Among its meanings, the word moral may refer to a passage in a story, usually in conclusion, that points out the lesson to be learned from the story. The word moral comes from the Latin <em>mores</em>, which means habits. Stories that present a moral at the end are generally trying to teach (especially children) about good and decent behaviors.
Maybe the most well-knows stories to contain a moral at the end are the fables. Fables are stories in which animals and inanimate objects present human emotions and the ability to speak. Their actions lead to a lesson to be learned by readers -- for instance: lying can cause harm to yourself and others; sharing is important; being conceited brings no good to no one etc.
All plots must have CONFLICT.
Themes are the broader ideas in a piece of work. And they are not specific to the plot. All plots must not have action, it can be other genres as well. All plots must not have dialogue, the plot can be entirely narrated.
On the other hand, a plot must have a conflict to define it and thereby develop it so that it catches the readers' eyes.
