Question #5538f
1 Answer
The spherical or oval shaped bacteria are termed as cocci.
Explanation:
Cocci (singular = coccus) have several distinct arrangements based on their planes of division as discussed below:
- Diplococcus and Streptococcus:
If division occur in one plane then it will produce either diplococcus or streptococcus arrangenment.
When cocci occur in pairs then the arrangement is called diplococcus.

Whereas, when cocci form chains then the arrangement is streptococcus.

- Sarcina:
When the division is in three planes, it produces sarcina arrangement. Sarcina is a cube of eight cocci.

- Staphylococcus:
When division is in random planes, it leads to staphylococcus arrangement. In this, cocci are arranged in irregular, often grape-like clusters.
