A kaon is a type of quark right? Is a way of thinking about it similar to the way a cell becomes specialized: a Kaon would be like a specialized quark?

A kaon is a meson (quark-antiquark pair) that contains a strange quark and either an up or a down quark.
i.e.
$$K^- = (\bar{u}s)$$
$$K^+ = (u\bar{s})$$
$$\bar{K}^0 = (\bar{d}s)$$
$$K^0 = (d\bar{s})$$
