What type of Placentation is found in the ovary of citrus and pea?

What type of Placentation is found in the ovary of citrus and pea?

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. This type of placentation is found in peas. When the ovules develop on the inner walls of the ovary, the ovary is said to have parietal placentation.

What type of Placentation is found in sunflower?

The different types of placentation found in plants are: Basal placentation: The placenta is at the base (bottom) of the ovary and a single ovule is attached to it. Example: Sunflower, marigold. Parietal placentation: Here ovary is one-chambered but it becomes two- chambered due to the formation of the false septum.

What is Placentation describe its types with diagram?

Placentation - definition Placentation is the arrangement of ovules in the ovary of a plant. The given diagram shows the types of placentation such as basal, apical, parietal, marginal, axial and free central. ... Axil : Carpels are folded inward with ovules placed along the central axis of ovary e.g., tomato.

What is Placentation explain?

In biology, placentation refers to the formation, type and structure, or arrangement of the placenta. The function of placentation is to transfer nutrients, respiratory gases, and water from maternal tissue to a growing embryo, and in some instances to remove waste from the embryo.

What is difference between Actinomorphic and Zygomorphic?

Explanation: The actinomorphic plants are radially symmetrical that is these can be bisected into two same halves in more than one plane whereas, the zygomorphic plants have bilaterally symmetrical flowers that is these flowers can be bisected into two halves in only one plane.

Which type of symmetry exist in pea?


Why the flowers of pea plant are referred as Zygomorphic?

Answer. Zygomorphic symmetry- A flower can be divided into two equal halves in one particular vertical plane. e.g. pea, gulmohar, bean, etc.. and other members of Fabaceae family. They have a standard, ala, and keel; which can be divide into two equal halves in one particular vertical plane.
