1. FORENSIC BOTANY

2. Male Reproductive Structures
Called the stamen
Made up of the anther (produces pollen)
and the filament (supports the anther)

3. Female Reproductive Structures
Called the pistil
Made up of the stigma (the pollen lands here)
the style (connects the stigma and the ovary)
and the ovary (makes ovules)

4. Sterile Structures Petals: brightly colored parts of the flower
Sepals: green, leaf-like structures that support the flower and protect the bud before the flower blooms

5. Sterile Structures (cont.)
Calyx: term for all of the sepals
Tepals: when petals and sepals look the same, they are called tepals; this flower has 3 petals and 3 sepals

6. Pollen Pollen grains contain the male gametes
It is possible to create a pollen fingerprint by determining the number and type of pollen grains found in a geographic area at a particular time of year.

7. Collecting Pollen Evidence
Pollen samples are collected using clean tools and placed into sterile, sealed containers
Each tool is cleaned after each sample is taken, or a new one is used each time
Photographs should also be taken to help analyze samples

8. Analyzing Pollen Samples
Pollen samples are examined by using a microscope
Samples are compared to reference collections
