* Metabolism: They break down nutrients and produce energy for growth and reproduction.

* Growth: They increase in size and divide to create new cells.

* Reproduction: They replicate themselves through processes like binary fission.

* Response to stimuli: They can sense and react to their environment, like changes in temperature or the presence of nutrients.

* Adaptation: They can evolve and change over time to better survive in their environment.

While bacteria are simple in structure compared to more complex cells, they are incredibly diverse and play crucial roles in ecosystems, from decomposing matter to producing food.
