graphite has hexagonal crystals and diamond tetrahedron
Graphite is in sheets... And is quite slippery.
Pencil 'lead' does not contain crystals. It is a mixture of the element carbon (in the form of graphite) and clay.
Borax forms crystals with a Monoclinic Prismatic structure.
Most minerals have one crystal shape each, but that shape may be different for a different mineral. However there are a few substances which form different shapes of crystal under different conditions. This is called polymorphism, or allotropy if the substance is an element. For instance carbon can form graphite or diamond.
It is smooth. Graphite is made up of crystals. It will have angles.

crystals are blank that have had a chance to grow and take shape.
Crystals do not give energy!

igneous is the texture of igneous rocks. The texture of igneous rocks is defined by 3 ways: a) Crystallinity- it expresses the degree of formation of crystals in an igneous rock. the texture of an igneous rock may be Holocyrstalline (Completely characterised by crystals, Hemicrystalline (partially having crystals) and holocrystalline (no crystals). b) Granularity- it is the size of the grains. it may be equigranular (when mineral grains are equal in size) or inequigranular (when mineral grains are not equal in size). c) shape of crystals- The shape of crystals may be Euhedral (When all crystals are of same shape), Subhedral (when they are partially similar in shape), Anhedral (when they are completely different in shape).
the way its crystals are formed
Yes, they can "grow".
