Magnetic Yeast Only a few organisms can actively sense and utilize magnetic fields. Magnetotactic bacteria contain strings of iron-dense membrane-bound organelles filled with magnetic crystals called magnetosomes, which act like microscopic compasses. Bacteria that contain magnetosomes can detect the earth’s magnetic field, telling them which direction is up and helping them find oxygen closer to the surface of the water.
