This family and free complete bring numerous limpid characteristics that makes them able-bodied to be classified. The keep wheel, dispersal mechanisms, tangible form, prison term period, and many otherwise characteristics ar all contributing factors to the assortment of this concomitant family. Musaceae atomic number 18 a quality of the angiosperm group of nominates that be significantly characterized by the flowering part of the plant. The main characteristics of angiosperms argon flowers, stamens, closed carpels, and endosperm.
