1. Embryo is diploid and      1.Zygote is haploid and     1.  it is Diploid and

unicellular.                                 unicellular.                            Multicellular.

2. it is the secondary state 2. it is the primary state     2.it is the

      after fertilizations.                  after fertilizations.          tertiary and

                                                                                                   last stage of
