Explain types of placentation
In biology, placentation refers to the formation, type and structure, or arrangement of placentas. The function of placentation is to transfer nutrients from maternal tissue to a growing embryo.

User: Discuss Types of placentation in flowering plants





Weegy: In flowering plants, placentation occurs where the ovules are attached inside the ovary. The ovules inside a flower's ovary (which later become the seeds inside a fruit) are attached via funiculi, the plant equivalent of an umbilical cord. [ The part of the ovary where the funiculus attaches is referred to as the placenta. Plant placentation types include: Basal placentation: The placenta is at the base (bottom) of the ovary. Simple or compound carpel. Apical placentation: The placenta is at the apex (top) of the ovary. Simple or compound carpel. Parietal placentation: The placentas are in the ovary wall within a non-sectioned ovary. Compound carpel. Axile placentation: The ovary is sectioned by radial spokes with placentas in separate locules. Compound carpel. Free or central placentation: The placentas are in a central column within a non-sectioned ovary. Compound carpel. Marginal placentation: There is only one elongated placenta on one side of the ovary. This is conspicuous in legumes. Simple carpel. ]
