BASAL PLACENTATION Meaning and
Definition
-
Basal placentation refers to the arrangement and attachment of the placenta within a flower. The placenta is the structure where the ovules, which develop into seeds after fertilization, are located.
In basal placentation, the ovary of the flower is superior, meaning it is positioned above the attachment point of other flower parts. The placenta, which contains one or more ovules, is located at the base or bottom of the ovary. As a result, the ovules develop from the lower portion of the ovary. This arrangement can often be observed in flowers with a single carpel, which is the female reproductive structure of the flower.
In basal placentation, the ovules are usually attached to the ventral suture, which is the seam running along the center of the ovary. Depending on the specific arrangement, basal placentation can be classified into various types, such as axile, parietal, or free central placentation.
Basal placentation is different from other types of placental arrangements, such as marginal or laminar placentation. These types involve the attachment of placentas along the edges or walls of the ovary, rather than at the base.
The arrangement of the placenta in a flower is an important characteristic that can help identify and classify plant species, providing useful information for botanical studies and research.

Etymology of BASAL PLACENTATION
The word "basal" in "basal placentation" comes from the Latin word "basalis", which means "pertaining to the base". The term signifies that the placentation occurs at the base or bottom part of the ovary in plants.
The term "placentation" also has its roots in Latin. It is derived from the Latin word "placenta", which means "cake" or "flat cake". Placentation refers to the arrangement or position of the placenta within the ovary of a flowering plant, where the placenta is involved in nutrient transfer between the mother plant and the developing seeds or embryos. Thus, "basal placentation" describes the specific arrangement of the placenta at the base of the ovary.
