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 (genetic material, dark blue) and the nucleolus (green). Transport vesicles (orange spheres) carry material to and from the endoplasmic reticulum (light blue) and Golgi apparatus (purple). Mitochondria (small yellow particles) provide energy.
