Geometrical question: how can you move an apple in such a way it seems not moved?

(in technical words: which are the isometries or rigid movements preserving an apple)

In other words , it seems that you can rotate an apple around the axis , in any way...
but looking better, and splitting the apple by a cut perpendicular to the axis, you see the five seeds, so that you can rotate the apple just of 72 degrees, 144 degrees... and so on

More difficult to explain by words than to show using a true apple. Try!
