Organelles

Eukaryotic cells have various smaller membrane bound regions inside them, which may have started as symbionts. Typical organelles are

►    mitochondrion

►    chloroplast - where light energy is converted into ATP molecular energy in plants

►    lysosome - where proteins are digested

►    cell nucleus

►    Golgi complex - where the proteins due to be released from the cell are assembled

►    peroxisomes (in animals) and glyoxisomes (in plants) - where fatty acids and amino acids are degraded

►    flagella and cilia - hairs which give the cell mobility or move liquids past the outside of the cell
