One strip of 8 related 35 mm images photographed through a microscope called photomicrographs. Arrows and call outs help the student locate important features. The film is mounted in a clear plastic holder that protects it on both sides.

Each microslide strip contains the following photomicrographs:
1. Sporophyte leaf (43X)
2. Spore cases (80X)
3. Germinating spores (80X)
4. Mature gametophyte (20X)
5. Sex organs (240X)
6. Archegone (480X)
7. Embryo sporophyte (12X)
8. Young sporophyte (3X)

Each microslide is accompanied by a detailed lesson plan designed to stimulate, inform, and question students about the topic under study. Each lesson plan has a pocket in which the microslide is stored. Lesson plans are printed on heavy card stock and will serve for repeated use.
