Evolutionary History Of Bananas

Evolutionary History of The banana tree Family and flowering make ups The banana family more formally known as banana family is a flowering nominate or angiosperm(http://theseedsite.co.uk/musaceae.html). This family and free rotatory slang numerous hard-hitting characteristics that makes them able-bodied to be classified. The life history sentence wheel, dispersal mechanisms, tangible form, condemnation period, and many otherwise characteristics ar all contributing factors to the smorgasbord of this concomitant family. Musaceae ar a man of the angiosperm group of arranges that atomic number 18 importantly characterized by the flowering part of the plant. The main characteristics of angiosperms ar flowers, stamens, closed(a) carpels, and endosperm. The earliest dated fossil 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 very started to go forth intimately 100 million geezerhood ago in the mid-cretaceous period. Angiosperms have been dominant ever since, they atomic number 18 the most progress plant group in closely every way. The physical features of the angiosperm are what really sets them apart. The flowers are made up of petals and stamens and chromosome mapping 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 fitting 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 another(prenominal) advantage for angiosperms compared to other plant groups. Endosperm is a tissue that contains nutrients for the embryo, seedling, and cotyledons. It helps cling to and provide commissariat for the seedling. The life cycle of angiosperms is pretty similar to the life cycle of gymnosperms with a few significant differences. Gametophytes of angiosperms are physically smaller. The microgametophyte of the pollen impress moreover has three cells, and in the ovule the...If you wishing to get a integral essay, order it on our website: Orderessay
