Explain types of placentationWeegy:
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. Placentation is best known in pregnant female mammals (eutheria), but also occurs in other animals, eggs (yolk sac placentation) and flowering plants.http://en.wikipedia.org/wiki/PlacentationAuto answered|Score .5666User:

I'm sorry that that wasn't a good answer. Please hold on while I contact an expert.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. ] Expert answered|dennis003|Points 810|
