You have studied
Give all the formulas in cell division ?
plants dont have centrioles, so how are the spindle fibres formed for cell division? how can it divide without centriole? n if it can , why do animals need the centriole? What is its main function? arent spindle fibres formed by centriole? if nt then wer r they formed?
