Due to the fact that the white blood cells can change their shape and squeeze in through smaller parts of the blood flow, they have the ability to protect the immune system from any infections. They able to move easily in the blood flow, meaning that they can stop any infections or illnesses that would have came the person's way. This is why a person that has more white cells is not ill that often because there are more cells able to reach that particular place of infection.
Chromatin is within the nucleus and is found in BOTH eukarayotic and prokaryotic and is a condensed structure of DNA,proteins, and RNA. It basically protects the DNA sequence and structure. It allows for mitosis and meiosis to happen. The nuclelous is located inside the nucleus but ONLY in eukarayotic cells. It makes ribosomes.
