All eukaryotic cells have within them a variety of different structures called organelles. Organelles are small and function much like organs function in a large organism. Some organelles are responsible for gathering cell energy, others for controlling cell activities. Plant cells have different organelles than animal cells but also share many also. They all have a large variety of sizes and functions and make life as we know if possible. Click the links in the yellow boxes for more detailed information on each of the organelles.
