Evolutionary History Of Bananas

Evolutionary History of The Banana Family and angiosperms The banana family more formally known as Musaceae is a flowering determine or angiosperm(http://theseedsite.co.uk/musaceae.html). This family and free radical have numerous straightforward characteristics that makes them able-bodied to be classified. The life wheel, dispersal mechanisms, tangible form, judgment of conviction period, and many otherwise characteristics atomic number 18 all contributing factors to the variety of this concomitant family. Musaceae ar a fraction of the angiosperm group of plants that argon importantly characterized by the flowering part of the plant. The main characteristics of angiosperms argon flowers, stamens, unopen carpels, and endosperm. The earliest dated fogy of an angiosperm is calculated to be 125 million days ago in the cretaceous period (http://en.wikipedia.org/wiki/Flowering_plant). The majority of angiosperms very started to go forth about 100 million old ag e ago in the mid-cretaceous period. Angiosperms have been dominant ever since, they are the most progress plant group in some 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. This is 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 uniform 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 emergency to get a full essay, order it on our website: OrderCustomPaper.com
