Granite is composed of numbers of individual mineral crystals and these crystals of individual minerals can be referred to as grains. Due to the formative processes involving granite, individual mineral crystals may not have what is popularly thought of as a crystal form, although they truly are mineral crystals. Grains could also be crystals or particles of other rocks which make up some sedimentary rocks. The grain size is part of the determination of the rock's texture: fine-grained, coarse grained, etc..
crystals
Mineral grains are crystals or pieces of crystals that vary widely in chemical composition. There are over 4,000 different minerals that have been identified so far.
Basalt typically has smaller crystals than granite. This is because basalt cools and solidifies quickly on the Earth’s surface, limiting crystal growth, while granite forms beneath the surface and has more time for larger crystals to develop.
Yes, granite is an intrusive igneous rock which means that it formed under ground from slow cooling of magma. The slower the magma cools, the larger the minerals will be in the rock. Typically, granite has a medium-grained texture but it can have large crystals also. You can see the individual minerals without a hand magnifier.
Basalt can't see crystals and basalt is extrusive. Granite you can see the crystals and is intrusive.

Large grains, and crystals
Yes, granite is made from interlocking crystals of minerals such as quartz, feldspar, and mica. The crystals are formed under intense heat and pressure deep within the Earth's crust, resulting in the strong and durable characteristics of granite.
If a granite rock is made of smaller crystals, it would be called fine-grained or fine-grained granite.
Granite is a type of igneous rock that typically has interlocking mineral grains without visible gaps. These interlocked grains give granite its characteristic strength and durability, making it a popular choice for countertops and building materials.
Granite is formed from magma that cools slowly, deep below the earth's surface. Very coarse-grained granite, called pegmatite, is formed when the magma cools extremely slowly. Most granite is hard grained
Granite is a coarse-grained igneous rock, meaning it is made up of large interlocking crystals. These crystals form as the magma cools slowly beneath the Earth's surface, allowing for the growth of larger grains rather than small ones.

crystals
Slow cooling of igneous rocks typically forms large crystal grains. This is because slow cooling allows more time for mineral grains to grow, resulting in larger crystals. Examples of rocks formed through slow cooling and having large crystal grains include granite and gabbro.
Granite is a rock that typically has large mineral grains due to its slow cooling process deep within the Earth's crust, allowing for the growth of visible crystals. This gives granite its characteristic speckled appearance and coarse texture.
The texture of a rock consists of it's grain or mineral crystal size, the arrangement of the grains or crystals, and the degree of uniformity of the grains or crystals. Examples of rock texture would be: * Coarse grained--visible crystals or grains as in granite. * Fine grained--small grains, invisible to the unaided eye as in shale. * Porphyritic--large visible crystals in a fine grained matrix as in granite porphyry. * Schistose--layers of flattened micaceous minerals such as in mica schist. * Foliated--a metamorphic rock texture of parallel mineral banding as in gneiss. * Homogenous--same grain apperance in all directions as in basalt.
