Expert Answer:

Crystal  lattice is a structure of crystals where each lattice point represent an identical group of atoms. A group is sometimes called a basis. One can form basis vectors with which all lattice point positions can be expressed. The unit cell (I guess you mean the primitive cell) is the volume defined by the set of basis vectors. This is the smallest volume; there are no cells with smaller volumes.
 
Unit cell: crystal structure which is the smallest group of atoms possessing 
the symmetry of the crystal
Lattice: orderly array of points in a crystal in space.
