The division of cocci in three planes form Sarcina, which is a cube of _ Cocci?
Correct answer: C. 08
- A. 02
- B. 04
- C. 08
- D. 16
Explanation
Sarcina is a genus of bacteria that divides in three planes, resulting in the formation of packets of cells arranged in a cube-like structure. These packets, known as tetrads, consist of eight cells arranged in a 3-dimensional cubic configuration. Each of the three planes of division produces four daughter cells, resulting in a total of eight cells in the sarcina packet. Therefore, the cube of cells formed by the division of cocci in three planes is composed of eight individual cells.
