Conservation of charge requires that equal-magnitude charges be created on the plates of the individual capacitors, since charge is only being separated in these originally neutral devices. The end result is that the combination resembles a single capacitor with an effective plate separation greater than that of the individual capacitors alone.

Why does capacitance not depend on the material of the plates?
The differentiating factor is the area of the plate (More charge) to increase the capacitance and the separation between the two plates is a limiting factor. If you are new, I HIGHLY recommend you read the ENTIRE wikipedia page about capacitors and try to really think about why the equations are formulated as they are.
