Crystals
i think that basalt is the smaller crystals out of the two, as the crystals in granite are larger.
it depends on the heat, if it cool very quick then it has small crystals but if it cool very slowly than it is bigger the slower the cooling period the bigger the crystals
Covalent crystals are not necessarily opaque. Think of diamond, pure quartz crystals, pure aluminium oxide crystals these all are colorless and transparent.

No
Fluorite is normally odourless. However there is one location, Wölsendorf in Bavaria where there mineral is radioactive and this causes inclusion of elemental Fluorine to occur in the crystals. On fracture chemical reactions between the air and this Fluorine cause the formation of "Ozone" (which smells of electric sparks). This variety of Fluorite is therefore called Antozonite or "Stinkspar" .Also Fluorite crystals are sometimes oiled with mineral oils to make them appear more transparent for sale and these crystals can smell oily.
Ghost Crystals are crystals of crosslinked polyacrylamide.
NO CRYSTALS are not living!!!!!!!!!!!!!!!!!
Granite with larger crystals, basalt with smaller crystals.
you should talk about how crystals are formed and what type of crystals there are
Yes. Salts can form crystals (salt crystals).

It depends on the type of igneous rock. Intrusive igneous rocks such as granite have large crystals, extrusive igneous rocks may have small crystals as in basalt or no crystals as in pumice.
Crystals
diorite crystals are large and andesite crystals are small
You can eat some kinds of crystals... salt crystals and sugar crystals, for example. It's probably not a good idea to eat, say, quartz crystals, though.
