Granite is a light-coloured plutonic rock.
The most common plutonic igneous rock is granite. There are various types of granite based on whether the rock cooled above or below the surface of the earth. The major differences among these types of granitic rock is their crystalline structure.
Grain refers to particle or crystal size in rock.

Grain size increases in the process of recrystallization.

It depends on if it is intrusive or extrusive. If it is an intrusive rock, it is formed when magma hardens under the earth and has a larger grain size. If it is an extrusive rock, it is formed when lava hardens on the earth's surface and has a smaller grain size.
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.
