To investigate the effect of microwave irradiation on the physical property and morphological structure of cotton cellulose, cellulose fabric was treated with microwave irradiation at different conditions. A ROOT MORPHEME does not possess a part-of-speech meaning e.g. Because of its indeterminate growth habit cotton has the most complex morphology of any major field crop grown as an annual. Carpels: Carpels are female organs of flower. The morphology of cotton fibers was characterized using field emission scanning electron microscopy (FESEM, NovaTM Nano SEM 450, Hillsboro, Oregon, USA). Explain the morphological structure of cotton fiber Get the answers you need, now! A cotton plant starts from seeds. The seeds germinate in 5 to 10 days and the cotton plant begins its growth with two cotyledons (the seed leaves that form nodes opposite each other at the base of the main stem) until the plant forms true leaves (leaves produced subsequent to the cotyledons). The morphology included findings from many investigations since J. Percival but during the past 20 yr (1965-1985) studies have become steadily more detailed and sophisticated with the introduction of resin techniques for light microscopy and transmission- and scanning-electron microscopy.
