This has the potential to be a very long answer but I will try to be brief :) Structure is intertwined with function. Often, structure is what determines or enables function and this applies to molecules, macromolecules, and all the way up to organisms. If the structure of something is changed, often the function is too. One prime example of this is in proteins. This is why when they are denatured (their shape changes) they no longer function correctly.
Prokaryotic cells get energy by utilize different sources of carbon compounds.
Chromosomes are parts of a cell that carries genetic information inform of genes, they contain DNA molecules packaged around histone proteins. Diploid number of chromosomes means that a cell has both sets of homologous chromosomes while haploid is used to refer to a cell that has one set of chromosomes and therefore a single set of genes.Mitosis is a type of cell division that takes place in the somatic cells (body cells) resulting to two daughter cells with the same number of chromosomes as the parent cell (diploid). Therefore, in this case a somatic cell will have 48 chromosomes (diploid number 2n).
