Embryogenesis in Higher Plants
Revisit double fertilization in angiosperms (chapter 29)!
First zygote division: asymmetric; leads to later suspensor and globular proembryo
Suspensor: connection to endosperm (nutrient reserve)
Proembryo develops apical shoot and root meristem, ground meristem, procambium (vascular system); determines root-shoot-axis of young plant
