1. In humans, placentation takes place 7 8 days after fertilization. 2. Hubrecht�s most important work was in embryology and placentation of the mammals. 3. The ovary is inferior and has only one ovule, with basal placentation . 4. Decidualization plays an important role in promoting hemochorial placentation . 5. The flowers are perfect, ovary is superior and bicarpellated, with axile placentation . 6. Marginal placentation , each pistil bearing one locule, with one to many ovules. 7. Each carpel will usually have a distinct line of placentation where the ovules are attached. 8. During pregnancy, placentation is the formation and growth of the placenta inside the uterus. 9. After implantation of the embryo, the decidua further develops to mediate the process of placentation . 10. Each locule of the superior ovary has 2 ovules with axile placentation that are anatropous to campylotropous.
