Solution:

The zygote formed after fertilization divides unequally to form two cells - larger suspensor cell towards micropyle and a smaller embryonal cell towards antipodal region. The suspensor cells divide further to form a 6 to 10 cells and helping anchor the embryo. The embryonal cell divides to form a diad (two cells), then further forms a quadrat of four cells. The embryo divides multiple times to form a globular structure. If the plant is dicot, the globular embryo further takes the shape of a heart and later splits in two to form cotyledons.
Upto globular stage, the embryo development is similar in both, dicot and monot plant of angiosperms.
