In 4% of the flowers the solitary ovule was borne externally on the ovary. Each of the normal pistils contained a of the ovuleOf the flowers 96 had pistils of apparently normal size and structure In 4 of the flowers the solitary ovule was borne externally on the ovary Each of the normal pistils contained a single (Monocot and . Dicot. ). The zygote gives rise to an embryo by a predetermined series of cell divisions and cell differentiations . This process is called . embryogenesis. . The . embryo . then germinates and grows into an adult plant. In seed plants, embryogenesis occurs within the embryo sac of the ovule. . Assistant Professor. Dept. of Botany. Annai. . Vailankanni. . Arts . and Science College. Thanjavur. – 613 007.. Introduction. Endosperm is the tissue produced inside the seeds of most flowering plants around the time of fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. . The goal of embryo culture in an assisted reproductive (ART) programme is to improve the quality of embryos developing in the laboratory and the chances of successful delivery of a healthy baby.

Arts . and Science College. Thanjavur. – 613 007.. INTRODUCTION. Plant embryogenesis is the process that produces a plant embryo from a fertilized ovule by asymmetric cell division and the differentiation of undifferentiated cells into tissues and organs. . DR SHARMISTHA CHAKRAVARTY. DEPT OF ZOOLOGY. BARNAGAR COLLEGE,SORBHOG. introduction. Embryology is the study of development of embryo from zygote till it becomes an offspring. The different stages in the development of individual organs are known as ontogeny and the study of the history of development of species or race is called its phylogeny. .
