What are bacteria and why are they important?
Bacteria are microscopic, single-celled organisms that belong to the domain of prokaryotes. This means that they do not have a nucleus or other membrane-bound organelles in their cells. They are also very simple and small compared to eukaryotic cells, such as those of plants and animals.
Bacteria come in different shapes and sizes. The most common shapes are spherical (cocci), rod-shaped (bacilli), and spiral (spirilla). Some bacteria can also change their shape depending on the environment or the stage of their life cycle.

Bacteria have many useful applications, such as breaking down organic compounds, waste processing, cleaning up oil spills and toxic waste. They are also used in the pharmaceutical and chemical industries, molecular biology, biochemistry, and genetic research. Bacteria are needed to make antibiotics.

Good bacteria in the human body help with digestion, nutrient absorption, and vitamin production. They also protect against harmful bacteria and stimulate the immune system. Probiotics containing helpful bacteria can be taken to support gut health.
However, some bacteria can also cause diseases in humans, animals, or plants. These are called pathogens. They can infect various parts of the body and produce toxins that damage the cells or tissues. Some examples of bacterial diseases are tuberculosis, pneumonia, cholera, rickets, and plague.
