Worked practice questions
Rod-shaped bacteria are known as
- cocci (spherical)
- spirilla (spiral)
- spirochaetes (coiled)
- bacilli (rod-shaped)
Show answer and solution
Correct answer: D. bacilli (rod-shaped)
Rods are bacilli, from the Latin baculus meaning stick.
Staphylococci typically group together in the form of
- single curved rods
- long straight chains
- bunch of grapes clusters
- paired diploid cells
Show answer and solution
Correct answer: C. bunch of grapes clusters
Staphylococci cluster like bunches of grapes, while streptococci form chains.
