Similarities: Mint and coriander  both are herbs.
                     They have a nice flavour and aroma.
                      Both of them have some medicinal values.
                      Both of them are used for cooking.
                      Both are leafy vegetables.

Difference: Mint reproduces when a small piece of the stem is cut which contains 
                    small projections that appear from the nodes are sown in soil.
                    Coriander reproduces through seeds.(dhaniya).
                     Mint has a stronger flavour than coriander.
