It's even possible to make out structures within the cell, such as the nucleus, mitochondria and chloroplasts. Almost all of these particles come in "left-handed" and "right-handed" versions (see chirality). While massive spin-1 particles have three polarization states, massless gauge bosons like the gluon have only two polarization states because gauge invariance requires the polarization to be transverse to the direction that the gluon is traveling.
