Ovules are attached to the inner wall of special tissues which are called placenta, the ovules are attached by the small stalk called funicules. There are several type of Placentations i.e. Basal, Marginal, central, axile, parietal.

Placentation in Plants of Barbados is Marginal, Marginal Placentation is when in which the placenta forms a ridge along the ventral suture(The line of fusion where the margins of the mega-sporophypl join)  of the ovary and the ovules develop on two separate rows is known to have marginal placentation.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
