Answer:
megasporogenesis. [ mĕg′ə-spôr′ə-jĕn′ĭ-sĭs ] The formation of megaspores inside the ovules of seed plants. A diploid cell in the ovule, called a megasporocyte or a megaspore mother cell, undergoes meiosis and gives rise to four haploid megaspores.
syncarpous - (of ovaries of flowering plants) consisting of united carpels. plant life, flora, plant - (botany) a living organism lacking the power of locomotion. apocarpous - (of ovaries of flowering plants) consisting of carpels that are free from one another as in buttercups or roses.
The placenta serves as an interface between the mother and the developing fetus and has three main jobs: Attach the fetus to the uterine wall. Provide nutrients to the fetus. Allow the fetus to transfer waste products to the mother's blood.
