What are some flower examples for basal placentation? - Quor

  1. Placentation is the arrangement of the ovules in the placenta and of the placenta in the ovary. — Basal placentation occur where one or few ovules develop at the base of a simple or compound ovary. • It is found in monocarpellary to a multicarpellary syncarpous ovary, usually a single ovule is attach at the base
  2. Types of Placentation : Axile,Marginal, Parietal, Basal, Superficial Placentation In Angiosperms, ovules are present inside the ovary. Placenta is a special type of tissue, which connects the ovules to the ovary. The mode of distribution of placenta inside the ovary is known as placentation
  3. Basal placentation involves a single ovule attached to the base of the ovary by a funiculus. One example of basal placentation is the sunflower, where each seed is attached to the base of the ovary..
  4. The arrangement of seeds in fruits depends on placentation. The different types of Placentation found in angiosperms are marginal, axile, parietal, free central, basal, and superficial; for example, pea shows marginal placentation whereas tomato shows axile placentation. The primary significance of Placentation is protecting the developing ovules
  5. Placentation refers to the formation, type and structure or arrangement of the placenta. It is the attachment of ovules inside the ovary. Basal placentation is found in monocarpellary to a multicarpellary, syncarpous ovary, usually, a single ovule is attached at the base
  6. The placenta is situated on the meeting of two margins of subsequent carpels which may be two or more in number. In this type of placentation, the ovules develop on the inner wall of the ovary. Ovary has a single chamber but appears to be double-chambered because of the formation of a false septum called replum

Basal placentation occurs when the placenta is present at the base of the ovary and single ovule is attached to it. It is generally seen in the unilocular ovary of the family Compositae. A. Unilocular ovary shows basal placentation. B. Bilocular ovary shows parietal placentation The placenta is formed by the swelling up of cohering margins, and on the latter develop the ovules in rows. It occurs in bicarpellary or multicarpellary but unilocular ovary, e.g., Papaveraceae. Placentation in Plants: Type # 3 Placentation. The arrangement of ovules within the ovary is known as placentation. The placentation is of different types namely, marginal, axile, parietal, basal, central and free central. In marginal placentation the placenta forms a ridge along the ventral suture of the ovary and the ovules are borne on this ridge forming two rows. Example- pe Placentation, the first test of the embryo's differentiative and organogenetic capacity, accomplishes two critical events: attaching the conceptus to the uterus and bringing the fetal and maternal circulations into close proximity to facilitate effective gas, nutrient, and waste exchange. as occurs in the Apiaceae; basal, with a placenta at.

(2) Axile placentation. The placenta is axial and ovules are attached to it in a multilocular ovary. Example: Lemon (3) Parietal placentation. Ovules develop on the inner wall of the ovary or on the peripheral. It is single-chambered, but due to the formation of a false septum, it becomes two-chambered. Example: Mustard (4) Basal placentation IMPLANTATION. Implantation involves the initial attachment of the trophoblastic wall of the blastocyst to the endometrial luminal epithelium. The trophoblast lineage gives rise to three main cell types in the human placenta: the syncytiotrophoblast, which forms the epithelial covering of the villous tree and is the main endocrine component of the placenta; the villous cytotrophoblast cells.

Normal placentation Definitive placenta. The definitive placenta forms at 9-12 weeks of gestation and is made of: The maternal blood flows through intervillous space and drains into uterine veins through the basal plate..

Placentation: Basal DISC FLORETS Position: Arranged in the central part of the capitulum. Flower (Floral characters): Bracteate, sessile, complete, tubular, actinomorphic, pentamerous bisexual and epigynous. Calyx: Reduced and modified into 2-3 scales called pappus With free central placentation the ovules are borne by a central column; this arrangement characterizes lysicarpous gynoecia. In apical and basal placentation, the placentas are located at the apex or base of the ovary, respectively. The most primitive type of placentation is laminar, with placentas scattered over the inner surfaces of the carpel Free-central placentation resembles axile placentation; however, the column is not connected by partitions to the ovary wall, and thus no locules are formed.

During the process of placentation, trophoblast cells attach to the basal membrane surrounding the stroma of these two types of villi. In the villi, the trophoblast cells fuse to create an external layer called syncytiotrophoblast; at the distal end of the anchoring villi, the trophoblast breaks the basal membrane and forms trophoblast cell.
