Here you can see a choromosome, that is composed by DNA and has a particular structure: here tehre is a duplicated chromosome, a single one has only one chromatide that is as you can see in the picture is the entire arm of a chromosome. Chromatin is the material of which is composed the chromosome, DNA enveoped around proteins called histons; centromer is the part of chromosome where two chromatid attack, where occur chromosome division and where splindle attack durig cell division; it separates long arm from short arm.
Centrioles are the part of a centrosome that is very important because it generates the mitotic splinde very important for cell division.
