Explanation

In plant embryogenesis, the apical cell of the 2-celled embryo develops into the embryo proper (bulk of the embryo), while the basal cell forms the suspensor and root apex. The torpedo stage shows clear differentiation of root and shoot, and the globular stage precedes cotyledon emergence. This developmental sequence follows the standard pattern in dicot embryogenesis.
