A pair of maternal and paternal chromosomes. E.g. the maternal and paternal version of chromosome 1.
Having a single set of unpaired chromosomes (Human haploid cells have 23 chromosomes)
Having two complete sets of chromosomes, one from each parent (Human diploid cells have 23 pairs of chromosomes)

Chromosomes form sister chromatid pairs following replication (as shown in the diagram)
The material of which chromosomes are composed of, and will unwind into.
An organelle involved in producing spindle fibres during cell division, made up of a pair of centrioles.
Each component of a pair forming the centrosome.
The centre of sister chromatids to which spindle fibres attach.
Fibres used to attach to the centromere of sister chromatids, which contract to separate each chromatid.
