Square of four cocci is_:
Correct answer: A. Tetrad
- A. Tetrad
- B. Sarcina
- C. Diplococcus
- D. Streptococci
Explanation
A tetrad refers to the arrangement of four cocci in pairs of two, forming two sets of pairs atright angles to each other. This arrangement gives the appearance of a square of four cocci. Tetrads are often observed in bacterial cell division where cocci remain attached after division. This arrangement is distinct from other pattems, making it the correct answer.
