Consult the annotated diagram for the sequential phases of dicot embryonic development:- Dicot embryonic development proceeds through identifiable stages: - Globular stage: Characterized by the formation of a spherical cell mass. - Heart-shaped stage: Cotyledon emergence begins, imparting a heart-like contour to the embryo. - Torpedo stage: Cotyledons lengthen, and the shoot and root meristems become clearly discernible. - Mature embryo stage: The embryo comprises two cotyledons, a plumule (apical shoot), and a radicle (apical root), prepared for germination.
