Embryo development:-

• The embryo develops at the micropylar end of the embryo sac where the zygote is situated.
• Most zygotes divide only after the formation of a certain amount of endosperm. This is an adaptation to provide nutrition to the developing embryo.
• Though the seeds differ greatly, the embryogeny (early embryonic developments) is similar in monocotyledons & dicotyledons.
• The zygote gives rise to the proembryo and subsequently to the globular, heart-shaped, and mature embryo.
