Scientists with the Forensic Biology discipline examine evidence for the presence of body fluids such as blood and semen as well as conduct DNA analysis on evidence containing these body fluids and touch DNA samples..
Forensic botany is all about plant identification.
This may be identifying a plant-based toxin that was used to poison someone or the hairs of a leaf that are clinging to a murder suspect's jacket.
With a whole plant, or pieces of a plant like leaves or wood, DNA analysis can be used to identify the specimen..
Botanical evidence in forensic investigations includes various types of plant material that can be used as physical evidence in criminal cases.
These include wood evidence, pollen analysis, plant growth rates, diatoms, and plant DNA typing..
Forensic biology is the application of genetics, cell and molecular biology, and chemistry to link a person(s), whether suspect or victim, to a place, an object(s), or another person.
Such linkages can be used to further investigations for both criminal and civil cases..
Forensic science technicians work in laboratories and on crime scenes.
At crime scenes, forensic science technicians typically do the following: Analyze crime scenes to determine what evidence should be collected and how.
Take photographs of the crime scene and evidence..
DNA profiles generated from evidence can then be compared to DNA samples from victims and other subjects involved in a case.
Forensic Biology analyzes evidence from a wide range of cases, including property crimes as well violent crimes such as sexual assaults, homicides, and robberies..

Forensic botany is the use of plant evidence in matters of law.
While plant fragments are often collected as trace evidence, they are only occasionally identified using microscopy and are still more rarely assessed using molecular biology techniques for individualization and sourcing of a sample.

In forensic botany it is mainly used for species identification, endemism of the subject plant.
During the course of plant species identification in the field for general academic purposes one gathers maximum morphological character in the field note book to identify the plant up-to species level.
