答无丝分裂是细胞分裂的一种方式,与有丝分裂比较,由于在分裂过程中不形成染色体、纺锤体;核仁、核膜不消失,因此比较简单,分裂迅速,耗能小,在分裂过程中可以继续执行细胞的功能,而不干扰代谢,因而具有高度的适应性,在动植物细胞分裂中均有发现。无丝分裂方式多样,最普遍的是一种直接分裂的形式,核仁先分裂,当中连以细丝,然后核拉长成哑铃形或“8”字形,继而核拉断成两块,这时细胞质随着分裂,并在滑面内质网参与下形成细胞膜,成为两个细
Answer: Amitosis is a way of cell division. Compared with mitosis, chromosomal and spindle bodies are not formed during mitosis. Nucleolus and nuclear membrane do not disappear, so it is relatively simple, rapidly dividing and consuming less energy. During the process of division In the cell can continue to perform the function, without interfering with metabolism, which has a high degree of adaptability in animal and plant cell division are found. A variety of amitosis, the most common is a form of direct split, split first nucleoli, which even the filaments, and then the nucleus into a dumbbell or “8” shape, and then nuclear break into two, which When the cytoplasm with the division, and in the slip of the endoplasmic reticulum to form a cell membrane, into two thin
