Help with mitosis Mitosis versus meiosis


In many organisms, particularly plants, the two daughter cells produced by meiosis I begin immediately to prepare for the second meiotic division. In others, however, nuclear envelopes temporarily appear and enclose each of the two separated sets of chromosomes between telophase I and prophase II, and there is a period of rest. This period, during which envelopes are again visible, is called interkinesis (pronunciation: in-ter-kuh-NEE-suhs). Each chromosome is still composed of two sister chromatids. The period between meiosis I and meiosis II is sometimes called "interphase," this is confusing because it is not a true interphase such as that seen between rounds of mitosis because no synthesis occurs (all chromosomes have two chromatids throughout this stage).
