Abstract
During starvation the filamentous mitochondria are reduced to granules or they may form large vesicles. In extreme starvation they break down to osmiophil spheres or cytolysomes. After feeding the nucleolus enlarges, RNA is synthesized, the mitochondria become filamentous and break up into rows of granules. The cells become distended with watery vacuoles. These changes are delayed if the tracheae to the fat body are cut Mitosis is little affected. Each fat droplet carries a ''catalysome'' or enzyme site at which esterase, NAD-diaphorase and the dehydrogenases of the Krebs Cycle are concentrated. The cataly-somes are probably concerned in lipid transfer.
