Primitive unit cell:-
The unit cell in which the constituent particles are present only at the corners are called “simple unit cells” or “primitive unit cells”.
Face centred:-
When particles are present not only at the corners, but also at the centre of each face of unit cell, it is called face centred unit cell.
End centred:-
When in addition to the particles at the corner, there are also the particles at the centre of any of two opposite faces it is called end centred unit cell.
Body centred:-
When in addition to the particles present at the corner one particle is also present at the centre of unit cell it is called body centred unit cell.

Bravais Lattices:-
The fourteen lattices corresponding to seven crystal systems are known as the bravais lattices.
We generally represents the unit cells by three dimensional arrangement of spheres.
Coordination Number:-
The coordination number of any constituent particle in a given unit cell is the no. of particles touching that particle.
