There are ways in which bacteria can survive if environmental conditions become inappropriate and harsh, such as extreme temperature change, water scarcity, etc. These include:
A. Internal spores:
* Internal spore: It is a latent cell that resists harsh conditions such as (high temperature, extreme cold, drought, ultraviolet radiation).
When the conditions improve, the spore grows into a new cell (this method is not considered a breeding method because it does not lead to a numerical increase).
B mutations:
Is a random change in the order of genes in the chromosome (DNA) resulting in new forms of genes and new traits and genetic diversity.
Genetic mutations therefore help bacteria survive in a constantly changing environment.
