Cell Division Vocabulary diploid (2N) – a cell with 2 chromosome sets in each of its cells; all body (somatic) cells haploid (N) – a cell with 1 chromosome set in each of its cells; all gametes (sperm, eggs) Cell Division 2 kinds of cell division: Pancreatic cells 2 kinds of cel...

cell division CELLDIVISION CELLDIVISION •细胞分裂（celldivision）•有丝分裂mitosis是活细胞增殖其数目由一个细胞分裂为两个细胞的过程。分裂前的细胞称母细胞，分裂后形成的新细胞称子细胞。一般包括细胞核分裂和细胞质分裂两步。在核分裂过程中母细胞把遗传物质传给子细胞。在单细胞生物中细胞分裂就是个体的...

Our demonstration of exceptionally fast cell division for marine invertebrates (sponges), as well as our ability to subculture the cells, is a breakthrough in marine biotechnology. From this study, we conclude that optimization needs to be species-specific and may depend on the intended use of ...
Cell Division What is the function of cell division? Unicellular organisms use cell division as a way to reproduce. Multicellular organisms use cell division in growth, development, repair, and reproduction. The nucleus contains genetic material. The genetic material is called DNA. DNA contains infor...
Telophase The chromosomes lengthen and become invisible again A nuclear membrane forms around the chromatin at each of the two ends (poles) of the cell The spindle fibres break down The nucleoli reform. At this stage nuclear division is complete as the nucleus of one cell has become two, howe...
