Organelles are structrues found in the [[cytoplasm]] of [[cells]] that carry out specific functions. Those functions include storing and breaking down food, storing [[DNA]], producing [[proteins]], and capturing the sun's energy through [[photosynthesis]]. Just like their name states, they act as little organs within each cell. The [[nucleus]], [[mitochondria]], and [[chloroplasts]] are the only organelles that contain DNA. The [[Endosymbiotic Theory]] explains why mitochondria and chloroplasts contain DNA.
