An example of autophagic vacuoles that resist digestion and persist as membrane-bound residual bodies.

Explanation
Lipofuscin granules are an example of autophagic vacuoles that resist digestion and persist as membrane-bound residual bodies. Lipofuscin is a yellow-brown pigment that accumulates in cells as a result of the incomplete degradation of lipids and proteins. These granules are commonly found in aging cells and are considered to be a hallmark of cellular aging. They are resistant to degradation by lysosomal enzymes and can persist in the cell for long periods of time. Therefore, lipofuscin granules fit the description of autophagic vacuoles that resist digestion and persist as membrane-bound residual bodies.
