Lysosomes • About as big as a mitochondrion • not much to see Function: degradation of proteins Present in animal cells, plant cells have similar organelle called peroxisome Number per cell varies enormously
Chloroplasts • Stacks of “grana” • grana composed of thylakoid disks Function: photosynthesis Present in photosynthetic cells 50-200 per cell
