About this mock
This mock test covers the principles and laboratory methods that make palynology a powerful tool in legal investigations. Questions examine how pollen moves through the environment, where it settles, and how long it persists on clothing, vehicles, soil, and other substrates encountered in forensic casework. The chemical preparation steps that transform raw evidence into interpretable assemblages are tested alongside the interpretive reasoning specialists must apply when linking a pollen assemblage to a geographic source.
The mock is designed for students, MSc and BSc learners, and practitioners of forensic botany and palynology who are building competence beyond basic taxonomic identification. Questions on pollen provenance draw on landmark casework including the Magnus aircraft-hijack investigation. The diatom section tests knowledge of frustule architecture, raphe function, and habitat ecology that underpins both drowning investigation and environmental provenance work. A melissopalynology section tests knowledge of honey pollen analysis as applied to geographic and botanical authentication.
Topics covered:
- Pollen dispersal vectors and deposition gradients
- Persistence of pollen on surfaces and textiles
- Acetolysis, KOH treatment, and mounting protocols
- Reference collection use and assemblage interpretation
- Pollen as provenance and trace evidence in casework
- Melissopalynology and honey authentication
- Diatom frustule morphology and taxonomic classification
- Ecological zonation and habitat specificity of diatoms
Each question presents near-neighbour options requiring careful concept discrimination.
Allow 30 minutes.
