Concept explainers
To tell:
Why binary fission generates chains of cocci in some species and cluster of cocci in some other strains.
Introduction:
Prokaryotes widely exist in three different shapes: spherical (cocci), rod (bacilli), and spiral (spirochetes). An example for a spherical-shaped bacterium is Staphylococcus sp. Staphylococcus is a gram-positive cocci structured as grape-like clusters. If viewed under a microscope, these bacteria appear as round and are clustered together.
Explanation of Solution
The prokaryotic cells are arranged in different forms during binary fission. For example, cocci in chains (streptococci) result from the division in one plane and when daughter cells fail to separate. Cocci in irregular or grape-like (staphylococci) arrangement is due to cell division in three planes and daughter cell failing to separate.
The prokaryotic cells exist in different forms (cocci in chain, pairs, and in grape-like structures).
