有丝分裂yǒusī-fēnliè植物细胞繁殖的一种方式。细胞成熟时,细胞核内出现一定数量的染色体,并形成细丝,密集在细胞的两极,排成纺锤形。后期染色体向两极移动形成两个新细胞。高等植物的细胞繁殖主要以有丝分裂的方式进行。{mitosis; a process of reproduction of plant cells. When a cell matures, a certain number of chromosomes appear in the nucleus. They form into thin fibres and, with the ends concentrating at the two poles of the cell, resemble the shape of a spindle. During anaphase the paired chromosomes separate at the kinetochores and move to opposite sides of the cell to grow into two new cells. The cells of higher plants are propagated chiefly by mitosis.}也叫also间接分裂{jiànjiē-fēnliè}。 |
