sentence: This lysosomal degradation process of cytoplasmic cell contents ensures survival of the organism in the absence of food , and also occurs in the late third instar larval stage and during metamorphosis.21 ,23 Under starvation , cells within the larval fat body undergo autophagy to provide nutrients to the developing imaginal tissues.24 ,25 In agreement with the other findings , autophagy was observed in cycG mutant larvae under feeding conditions : cells in the fat body showed a punctate staining with a lysosome-specific marker , which was also seen in starved but not in well-fed wild type animals ( Figure 1B ' - D ' ) .
