In everyday life, we never think about the amount of cells that we shield or produce; least the structure, size or shape. Often in forensic investigation, scientists come across different types of cells, especially human cell (like spermatozoa cell, while investigating an alleged rape) or human fluid (like bacteria, which could be found in the blood and use for DNA profiling.) These cells can help investigators to know more about a case for example, pollen and diatoms could help a scientist to decide the geographical area of an incident. If it is underwater, Diatoms would be found or land (pollen). It can help to decide the type of environment an incident occurred. Cells can also help to explain if an evidence or body has been transported from one place to the other, i.e. it helps to locate the original crime scene. For example, if a body was found in the bush, after experimentation, scientist might found out that the body has been transported from one place to another, if there is diatoms in the body, it might identify the movement of corpse.
