Fermions are usually associated with matter while Bosons are the force carriers. Examples of Fermions: Leptons (Electrons, Neutrinos etc), Quarks (Up, Down etc.), Baryons (Protons, Netrons etc.) ... This means that gluons will react with quarks but not with leptons.

What are fermions explain?

In particle physics, a fermion is a type of particle that obeys the rules of Fermi-Dirac statistics, namely the Pauli Exclusion Principle. These fermions also have a quantum spin with contains a half-integer value, such as 1/2, -1/2, -3/2, and so on.

What are fermions and bosons?

A fermion is any particle that has an odd half-integer (like 1/2, 3/2, and so forth) spin. ... Bosons are those particles which have an integer spin (0, 1, 2...). All the force carrier particles are bosons, as are those composite particles with an even number of fermion particles (like mesons).
