Question
What type of placentation is seen in sweet pea ?
Options
A.Axile
B.Rree central
C.Marinal
D.Basal
Solution
In sweet pea (Pisum sativum), the placentation is marginal, in which, the placenta develops along the junction of two carpels, in a unilocular ovary.
In basal placentaon, the ovules are few or reduced to one and are borne at the base of ovary rg, Compositae.
in axile placentaion, margins of carpels fold inwaeds, fusing together in centre of ovary to form a single central placenta. Ovaryis divided into as many locules, as there are carpls eg, Hibiscus, Asphodelus. Ferr-central placentation possesses a placenta arises as a central upgrowth from ovary base eg, Stellaria.
