Define the three major types of bacterial shapes. which of these did you observe in the exercise?

Three major types of bacterial shapes:

1. Cocci - are round cells, occasionally a little flattened when they are near each other.

2. Bacilli - are rod-shaped bacteria.

3. Spirilla - are curved bacteria that can range from a mildly curved shape to a corkscrew-like curve.

Coccus or cocci was observed in the experiment.

The three forms of bacteria are bacilli, coccus, and spirals.

Explanation:

Bacilli are characterized by being rod-shaped bacteria. The most common are those that cause tuberculosis, tetanus, etc. These types of bacteria inhabit different environments and can only be seen using a microscope. While coccus are bacteria with a spherical shape. And finally, the spirals are bar-shaped, spiral, or rigid.
