The answer is cocci.

There are three basic types of the shape of bacteria:
- Cocci - spheres,
- Bacilli - rods,
- Spirilla - spirals.

If a student drew a circular shape, that probably represented sphere. Therefore, the shape of seen bacteria was spherical which suggests that the bacteria must be cocci.
