Nucleus and Cell Division

| Description |
The nucleus is the most conspicuous organelle in the cell. It contains most of its genetic complement. This genetic information is passed on to the daughter cells during mitosis and cell division.[1]
In cell wall free endosperm cells of Haemanthus the various stages of mitosis can easily be observed. After prophase the chromosomes, which have already split longitudinally, align themselves on the metaphase plate. In anaphase they separate.[2]
This LaserScan shot shows a spindle apparatus with chromosomes attached to it in metaphase. It is from an animal cell.[3]
