Paper: Developmental Biology. Session: 2019-2020. Meaning of Placenta. The embryo, specially in eutherian mammals, becomes implanted to the ute­rine wall. The process of implantation in­volves tissue interaction and establishment of connection between the uterine wall and the extraembryonic membranes. The region of attachment between the embryo­nic tissue and the uterine wall is called the placenta and the process involved in im­plantation is called the placentation.. Dept. of Botany. Annai. .

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. . tissue and . their main function is to provide starch and other . nutrients.  to the growing . embryo. .

Your patient is aged 37 years and has had one previous fresh, day 5 embryo transfer with a single top-quality blastocyst. The previous transfer resulted in a negative pregnancy test.  .

A flower is defined as a modified shoot because it is a specialized structure developed to reproduce seeds. The function of the shoot is the transfer of water and nutrients. To perform the function of the reproduction, the shoots gets modified into flowers. The sepals and petals in flowers are considered as modified leaves. The shoot nature of a flower can be proved by citing the following major examples from the plant kingdom:-.
