Which type of placentation is seen 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.
What type of placentation is found in the ovary of citrus and pea?
Option C: Lemon has axial placentation as the ovules are present in and around the center of a compound ovary on an axis which is formed from a joined septa. Therefore, this is the correct option. Option D: Pea has marginal placentation and not axial placentation.
What is the placentation of seed in the fruit?
A multiple fruit is one formed from a cluster of flowers (called an inflorescence). Each flower produces a fruit, but these mature into a single mass. Placentation refers to the pattern of attachment of ovules within the ovary (see Fig. 2).
What type of placentation do sweet potatoes have?
The ovary in potato is bilocular, placenta is swollen with several ovules. This type of placentation is called axile.

Therefore, cereal grains, such as corn, wheat and rice are better considered edible seeds, although some references list them as fruits.
Which type of placentation is found in dianthus?
free central placentation
In free central placentation, the ovules are borne on the central axis without septa. Therefore, the type of placentation in dianthus is free central.
Which type of ovule is found in Dahlia?
Answer: Explanation: Campylotropous: ovule is curved more or less at right angle to funicle. micropylar end is bend down slightly e.g., in members of Leguminosae, Cruciferae (e.g., Capsella, Mustard).
What kind of placentation is seen in Sweet Pea?
In basal placentation, the ovules are few or reduced to one and are borne at the base of ovary e.g. Compositae. 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.
