What is the placentation of china rose?
axile placentation

What is the placentation of mango?
unilocular parietal
Placentation when unilocular parietal, or basal. Ovules in the single cavity 1; pendulous, or ascending; apotropous; with ventral raphe, or with dorsal raphe; non-arillate; anatropous. Fruit and seed features. Fruit fleshy; indehiscent; a drupe; 1 seeded (usually).
What is the placentation of Capsicum?

What is the placentation of tomato?
Axile type
Complete answer: Axile type of placentation is seen in lemon and tomato. In this type of placentation, the ovary is partitioned into two or more chambers by septa. The placenta is formed in the central region where all the septa intersect or meet and therefore an axle column bearing ovules is formed.

What is the significance of placentation?
The primary significance of Placentation is protecting the developing ovules. In addition, the placenta, which is arranged in the Placentation, provides nutrients to the developing embryo.

What is free central placentation?
Ans: Free central placentation is a placentation type in which the gynoecium is polycarpellary, and ovules borne at the center of the ovary, which is quite separate from the ovary wall by any septum. It is found in Primrose, Dianthus, etc.
What is placentation of ovules?
The ovules remain attached to the inner wall of the ovary to a parenchymatous outgrowth or cushion called the placenta. The mode of arrangement of ovules within the ovary is called placentation. The ovules present in the flower’s ovary are connected by funiculi. The Placenta is the part of the ovary where the funiculus is attached.
