WebbThe nucleus, most organelles and cytoplasm are displaced to the centrifugal end of the cell, while the vacuoles lie at the other end. However, after centrifugation, the preprophase microtubule bands (PMBs) are nucleated and remain at the expected position close to the guard cell mother cells (GMCs). Webb27 juni 2014 · The preprophase band ( PPB) is a faithful but transient predictor of the division plane in somatic cell divisions.
