How is th shape and size of a cell related to its function?

The shape of a cell dictates the function of that cell. This is more pertinent to animal cells that, unlike plant cells, do not have a rigid cell wall. A misshapen cell cannot properly perform its intended function

Chromosomes-a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.  

Chromatin-the material of which the chromosomes of organisms other than bacteria are composed. It consists of protein, RNA, and DNA.

Chromatid-each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.

Centromere-the region of a chromosome to which the microtubules of the spindle attach, via the kinetochore, during cell division.

Centriole- a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
