Evolutionary History Of Bananas

Evolutionary History of The Banana Family and angiosperms The banana family more officially known as Musaceae is a flowering doctor 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 be all contributing factors to the com disunitementalization of this concomitant family. Musaceae atomic number 18 a part of the angiosperm group of plants that argon importantly characterized by the flowering part of the plant. The main characteristics of angiosperms be flowers, stamens, unopen carpels, and endosperm. The earliest dated fossil of an angiosperm is calculated to be 125 million geezerhood ago in the cretaceous period (http://en.wikipedia.org/wiki/Flowering_plant). The majority of angiosperms in truth started to go forth about 100 million ye ars ago in the mid-cretaceous period. Angiosperms have been dominant ever since, they are the most progress plant group in roughly 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 adapted than corresponding gymnosperm organs. The closed carpel develops into the fruit, which serves as an attractant to animals that will disperse the seeds. Thi s is some other advantage for angiosperms c! ompared to other plant groups. Endosperm is a tissue that contains nutrients for the embryo, seedling, and cotyledons. It helps nurse 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 trust to get a full essay, order it on our website: OrderCustomPaper.com
