Question: What Does A Forensic Palynologist Do?

Forensic palynology is the application of pollen and spores in solving legal issues, either civil or criminal.

What does a Palynologist do?

Palynology is the study of plant pollen, spores and certain microscopic plankton organisms (collectively termed palynomorphs) in both living and fossil form.

How can a forensic Palynologist help a crime investigation?

objects, people and places that pertain to both criminal and civil cases. A forensic palynologist can help a crime investigation because they can examine the pollen in the victim and compare it with the pollen from the suspects by using a comparison microscope to tell if it’s a match.

What does a forensic microbiologist do?

Forensic microbiology is the study of microorganisms in order to determine the path of an outbreak, the identity of a criminal or the origin of a particular strain of biological weapon or contagion.

Why is the pollen of Autogamous or self pollinating plants not important forensically?

Occurs in a small group of animals referred to as “autogamous”, they are self-pollinating and are so efficient that little pollen is needed. Like pollen produced by submerged plants, the pollen of autogamous plants is of little value in forensic work because it is dispersed in minimal numbers.

Why is palynology important?

Palynology is a particular study within the realm of ecology that deals with the pollen and spores of plant species. While this seems like a narrow biological field, the everyday palynologist has a plethora of potential career opportunities before them, as palynology has several unique uses in the modern world.

What is Sporopollenin and why is it important?

Sporopollenin is one of the most chemically inert biological polymers. It is a major component of the tough outer (exine) walls of plant spores and pollen grains. It is chemically very stable and is usually well preserved in soils and sediments.

Why are pollen grains important?

Pollen grains represent the male portion of the reproductive process in plants and trees. These tiny bodies are swirling in the air and on the legs of insects so that they can join the female part of the plant to create a new seed. This important process is known as fertilization.

Does pollen contain DNA?

To DNA barcode pollen, the first step is to extract the DNA. Pollen grains produce the male reproductive cells (sperm) of the plant. Each pollen grain has a tough outer layer called the exine, made of a protein called sporopollenin. We need to break the exine in order to release the DNA that’s protected inside.

What is pollen made of?

Pollen is a fine powder made up of microspores produced by male plants. It is also called flower sperm. Pollen carries the male gametes (reproductive cells) of seed plants. Seed plants include both conifers (plants whose seeds grow inside cones) and flowering plants.
