1. Name and draw the three basic shapes bacteria may take. Include the shape and the correct name for that shape.

Bacteria come in a variety of shapes, but the three basic ones are cocci, bacilli, and spirilla. Cocci are spherical bacteria, often forming clusters or chains like little balls. Bacilli are rod-shaped, resembling tiny sausages, which can be single or linked together. Spirilla are spiral or corkscrew-shaped, giving them a twisty appearance that helps them move through liquids. In addition to these forms, bacteria exhibit fascinating adaptive behaviors. For instance, some cocci can form protective biofilms, allowing them to thrive in harsh environments, while bacilli may produce endospores, enabling them to withstand extreme conditions like heat or dryness. Spirilla, on the other hand, often use their unique shape to navigate through viscous environments, making them exceptional swimmers in their aquatic habitats.
