Here is ur answer :

CRYSTAL LATTICE

Crystal lattice is the depiction of three dimensional arrangements of constituent particles (atoms, molecules, ions) of crystalline solids as points. Or the geometric arrangement of constituent particles of crystalline solids as point in space is called crystal lattice.

UNIT CELL

The smallest portion of a crystal lattice is called Unit Cell. By repeating in different directions unit cell generates the entire lattice.

Answer 2

♦ Crystal Lattice: It is the regular arrangement of the constituent particles (atoms, ions or molecules) in 3-D space.
♦ Unit Cell : The smallest portion of the crystal lattice which is repeated over and again in 3-D space and hence forms crystal lattice.

hope it helps!!
