Computer artwork showing the organelles in a eukaryotic cell. This is an animal cell. Structures include the nucleus (centre, orange) which has a membrane with nuclear pores. Inside the nucleus is the DNA. Transport vesicles carry material to and from the rough endoplasmic reticulum and Golgi apparatus (blue). Mitochondria (green) provide energy. Ribosomes (dark blue) carry out RNA translation and formation of proteins.
