FORENSIC BOTANY Male Reproductive Structures Called the stamen

FORENSIC BOTANY

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

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)

Sterile Structures Petals: brightly colored parts of the flower Sepals: green, leaflike structures that support the flower and protect the bud before the flower blooms

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

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.

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

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