Metaphase of cell mitosis. Image 3 of 6. Light micrograph of a bluebell cell (Endymion sp.) undergoing cell division (mitosis). A cell in the middle stages of mitosis, known as metaphase, is seen. Chromosomes can be seen within the cell as orange thread like structures. These have congreg- ated across the middle of the cell and are attached to a tubular structure (not visible here) known as the spindle. The spindle runs across this cell from left to right and, in the next stage of mitosis, will pull each chromosome apart into two identical chromatids which will form two "daughter" nuclei at either end of the cell. Part of sequence, images B215/045 to B215/050.
