What type of placentation is in sweet peas?
Marginal placentation
So, the type of placentation that can be seen in sweet pea commonly known as (Pisum sativum) is Marginal placentation. The second type is axile- In axile placentation when the placenta is axial and the ovules are attached to it in a multilocular ovary, the placentation is said to be axile.
Does pea have parietal placentation?
The ovary in which the placenta forms a ridge along the ventral suture of the ovary and the ovules develop on two separate rows is known to have marginal placentation. e.g peas. (B) Parietal placentation: When the ovules develop on the inner walls of the ovary, the ovary is said to have parietal placentation.

How many ovules are there in pea plant?
In this particular flower of the Pea, there are six ovules, but other flowers might have more or fewer. In B of Figure 39 is shown the ovary after it becomes a mature pod. The pod is opened to show the seeds. Each seed is a developed ovule and the pod enclos- ing the seeds is the ovary wall much enlarged.

Perisperm is the nutritive tissue surrounding the embryo in certain seeds and developing from the nucellus of the ovule. After double fertilization, the remnants of the nucellus of the ovule in the mature seed is called perisperm.
What type of placentation is seen in Sweet Pea?
> What type of placentation i… What type of placentation is seen in sweet pea? 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 placentation, the ovules are few or reduced to one and are borne at the base of ovary e.g. Compositae.
What is marginal placentation in Sweetpea?
In sweetpea (Pisum sativum), the placentation is marginal, in which the placenta develops along the junction of two carpels, in a unilocular ovary. In basal placentation, the ovules are few or reduced to one and are borne at the base of ovary. e.g. compositae.
What is axial placenta with example?
Axile placentation: The placenta is axial and the ovules are attached to it in a multilocular ovary. Example: China rose, tomato and orange. Free central placentation: The ovules are borne on central axis and septa are absent.
What is axial and free central placentation in plants?
In axial placentation, margins of carpels fold inwards, fusing together in center of the ovary to form a single central placenta. The ovary is divided into as many locales, as there are carpels, e.g. Hibiscus, Asphodelus. Free-central placentation possesses a placenta arises as a central upgrowth from ovary base, e.g. Stellaria.
