Evolutionary History Of Bananas

Evolutionary History of The banana tree Family and flowering localises The banana family more formally known as banana family is a flowering take a shit or flowering define(http://theseedsite.co.uk/musaceae.html). This family and free antecedent perk up numerous discrete characteristics that makes them able-bodied to be classified. The liveness wheel, dispersal mechanisms, tangible form, meter period, and many otherwise characteristics ar all contributing factors to the assortment of this concomitant family. Musaceae ar a dissipate of the angiosperm group of plants that atomic number 18 significantly characterized by the flowering part of the plant. The main characteristics of angiosperms atomic number 18 flowers, stamens, closed carpels, and endosperm. The earliest dated dodo of an angiosperm is calculated to be 125 million historic period ago in the cretaceous period (http://en.wikipedia.org/wiki/Flowering_plant).

Stamens are the male reproductive organs of a flower; they are comprised of a stalk, an anther, and pollen sacs.

Angiosperm stamens are lighter and more qualified than corresponding gymnosperm organs. The closed carpel develops into the fruit, which serves as an attractant to animals that will disperse the seeds. This is some other advantage for angiosperms compared to other plant groups. Endosperm is a tissue that contains nutrients for the embryo, seedling, and cotyledons. It helps value and provide commissariat for the seedling. The career cycle of angiosperms is pretty akin to the life cycle of gymnosperms with a few significant differences. Gametophytes of angiosperms are physically smaller. The microgametophyte of the pollen impress exclusively has three cells, and in the ovule the...If you neediness to get a climb essay, order it on our website: Orderessay
