Placentation is the arrangement of placentae and ovules in the ovary. There are different types of placentation:
1)marginal placentation
2)parietal placentation
3)axile placentation
4)free central placentation
5)basal placentation
6)superficial placentation
The Pride of Barbados flower has parietal placentation, where the ovules are borne along the inner wall (parietal) of the ovary. This type of placentation is common in plants with multi-carpellate, unilocular ovaries like those found in Pride of Barbados.
Seed plants are actually flowering plants. Since the plants reproduce the flowers bloom from the plants. The seeds are carried to different places by the wind. Other plants such as the fern are called seedless plants because ferns do not reproduce by seeds they reproduce by spores.Added:Excepting gymnosperms, which are seed plants that do not flower.
in seed plants, the plants that you see are in the
vascular
Angiosperms are flowering plants
Marginal placentation
The Pride of Barbados flower has parietal placentation, where the ovules are borne along the inner wall (parietal) of the ovary. This type of placentation is common in plants with multi-carpellate, unilocular ovaries like those found in Pride of Barbados.
Epitheliochorial placentation.
basal placentation
The type of placentation in the ovary of pea flowers is parietal placentation. This means that the ovules are attached along the walls of the ovary.
Oh, what a lovely question! Okra has a type of placentation called axile placentation. This means that the ovules are attached to the central axis or column of the ovary. It's like nature's way of arranging things beautifully inside the okra plant. Just like how we arrange colors on a canvas to create a masterpiece!
In apples, the type of placentation is known as axile placentation. Axile placentation occurs when the ovules are attached to the central axis or column of the ovary. In the case of apples, the ovules are attached to the central column within the ovary, which eventually develops into the core of the apple fruit. This type of placentation is common in fruits of the Rosaceae family, to which apples belong.
Dogs and cats have zonary placentation, where the placenta forms a band around the middle of the fetus's chorion. This type of placentation allows for efficient nutrient exchange between the mother and the developing embryos.
parietal
The placentaton is parietal.
Implantation occurs in the endometrium of the uterus, where the fertilized egg attaches and begins to develop. Placentation occurs in the placenta, which forms from tissue of both the mother and the embryo, providing nutrients and oxygen to the developing fetus.
I am sorry but not known is much regarding to Circumvallate Placentation. The best thing to do is speak to a professional in this area and discuss your options. I wish you all the best.
