. Embryogenesis in plants. Embryology. Fig. 53. Capsella bwsa-pastoris A classical example of embryogeny in a dicotyledon. Stages in the embryogeny illustrating Soueges' system of analysis and nomenclature {see also Fig. 55). The first transverse wall divides the zygote into an apical and a basal cell, ca and cb respectively. The products of these two cells and their respective contributions to the embryonic development are indicated; e, embryonic cell; su, suspensor; hy, hypophysis; s, position of shoot apex (semi-diagrammatic, after Soueges). G, Chelidomitm majits. Different types of proembr

The diversity in the early embryogeny of dicotyledons and monocotyledons depends largely on the nature of the further development of these two cells. The basal cell (i) may remain undivided with or without subsequent enlargement, or (ii) it may undergo further transverse divisions either {a) contributing to the embryo proper, or.
