Bacilli (singular)/Bacillus (plural): Rod-Shaped
Cocci (singular)/Coccus (plural): Round
Diplo (prefix): Two
Spirilla: Helix/spiral shaped, rigid
Spirochetes: Helix/corkscrew shaped, flexible
Staphylo (prefix): Grape-like clusters
Strepto (prefix): Chained bacteria
Vibrio: Comma-shaped bacilli
Part One: Draw what the resulting bacteria looks like based on the name
