Evolutionary History Of Bananas

Evolutionary History of The Banana Family and flowering plants The banana family more officially known as Musaceae is a flowering secure or angiosperm(http://theseedsite.co.uk/musaceae.html). This family and free radical have numerous unambiguous characteristics that makes them able-bodied to be classified. The life wheel, dispersal mechanisms, tangible form, period period, and many otherwise characteristics ar all contributing factors to the miscellany of this concomitant family. Musaceae ar a crack up of the angiosperm group of plants that argon importantly characterized by the flowering part of the plant. The main characteristics of angiosperms ar flowers, stamens, unopen carpels, and endosperm. The earliest dated fogey of an angiosperm is calculated to be 125 million age ago in the cretaceous period (http://en.wikipedia.org/wiki/Flowering_plant). The majority of angiosperms genuinely started to go forth about 100 million years ago in the mid-cretace ous period. Angiosperms have been dominant ever since, they atomic number 18 the most progress plant group in virtually every way. The physical features of the angiosperm are what really sets them apart. The flowers are made up of petals and stamens and function as the reproductive organs. 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 competent 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 so me other advantage for angiosperms compared ! to other plant groups. Endosperm is a tissue that contains nutrients for the embryo, seedling, and cotyledons. It helps cherish and provide commissariat for the seedling. The life cycle of angiosperms is pretty resembling to the life cycle of gymnosperms with a few significant differences. Gametophytes of angiosperms are physically smaller. The microgametophyte of the pollen impress only has three cells, and in the ovule the...If you pauperism to get a full essay, order it on our website: OrderCustomPaper.com
