How are plants used to solve crimes?
Plants are being used to help solve crimes. The pollen and seed s they can leave behind can often become key pieces of evidence. ... While plants aren't able to testify in court, they are able to provide evidence about guilt or innocence.
How can botanical evidence be used in forensics?
Botanical evidence may be used to identify clandestine (illegal) graves by examining the changes of disturbed soil and the plants that often begin to grow, and it may be used to establish drowning at a specific location through the identification of specific diatoms and algae that are present in the lungs of the ...
Why are plants considered to be a great forensic tool?
The reasons for this are several: 1) plant remains can be found almost everywhere; 2) they offer multiple sources of evidence, both macroscopic and microscopic, such as pieces of wood, (even as charcoal), seeds, fruits, leaves, twigs, plant hairs, microscopic air-borne pollen and spores, or in aquatic environments, ...
What evidence can be found at a crime scene?

What is a plant to a criminal?
Forensic botany, otherwise known as plant forensics, is the use of plants in criminal investigations. ... The aim is to link plant evidence with a crime, such as placing a suspect at a crime scene through analysis of pollen or seed particles found on their clothing.
What is the use of botany?
Botanical research has diverse applications in providing staple foods, materials such as timber, oil, rubber, fibre and drugs, in modern horticulture, agriculture and forestry, plant propagation, breeding and genetic modification, in the synthesis of chemicals and raw materials for construction and energy production, ...
What is pollen evidence?
Pollen can reveal where a person or object has been, because regions of the world, countries, and even different parts of a single garden will have a distinctive pollen assemblage. Pollen evidence can also reveal the season in which a particular object picked up the pollen.
How is botanical evidence collected?
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.
How can botanical evidence provide clues regarding where a crime was committed?
A forensic botanist can identify individual plants from tiny fragments found on bodies, automobiles, and other objects. ... It is possible to exclude possible crime scenes based on the habitat requirements of the recovered plant. Knowing a crime scene's assemblage of plants can help identify its location.
What type of plants produce pollen?
Both gymnosperms (cone-bearing plants) and angiosperms (flowering plants) produce pollen as part of sexual reproduction. In gymnosperms pollen is produced in microsporangiate cones (male cones or pollen cones), while in angiosperms pollen is produced in the anthers (part of the stamen within the flower).
What is the most commonly encountered plant in criminal investigations?
