crystal lattice
Each constituent particle is represented by one point in a crystal lattice.
These points are known as lattice point or lattice site.
Lattice points in a crystal lattice are joined together by straight lines.
By joining the lattice points with straight lines the geometry of the crystal lattice is formed.
unit cell
A unit cell is characterized by six parameters. These parameters are three edges (a, b and c) and angles between them (α, β and γ).
Dimensions along the edges of a unit cell is represented by a, b and c.
Edges of unit cell may or may not be mutually perpendicular.
The angle between b and c is represented by α, between a and c by β and between a and b by γ.

Answer:
The key difference between lattice and unit cell is that a lattice is a regular repeated three-dimensional arrangement of atoms, ions, or molecules in a metal or othercrystalline solid whereas a unit cell is a simple arrangement of spheres (atoms, molecules or ions) that resemble the repeating pattern of alattice.
