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