Ilustração de The interior of an eukaryotic cell. This is the most common generic type of cell and it's present in all mammals.

In the center is the nucleus (the perforated sphere), inside of it is the nucleolus (the bright sphere). Around the nucleus there's the Rough Endoplasmic Reticulum (the wavy orange half sphere), covered with Ribosomes (blue dots). Around it is the Smooth Endoplasmic Reticulum (the tube like orange body). Both Rough and Smooth Endoplasmic Reticulum are cut in half to let the nucleus visible. There are orange vesicles (Lysosomes) traveling from the Smooth Endoplasmic Reticulum to the Golgi Apparatus (in purple). The greenish bodies are the Mitochondria. The dark lines are the cytoskeleton and through them there's some brownish spheres that are nutrients traveling to the nucleus. The bright green tube like structures are Centrioles and the white spheres represent the various elements that travel randomly inside the cell like elements for recycling and nutrients.
