Bacterial behavior refers to the ways in which bacteria interact with their environment and each other. These microorganisms can move toward nutrients or away from harmful substances through a process called chemotaxis. They can also communicate with one another using chemical signals in a process known as quorum sensing, which helps them coordinate activities like biofilm formation. Bacteria exhibit various growth patterns and can adapt to changing conditions. Some bacteria form spores to survive extreme environments, while others can exchange genetic material through conjugation, enhancing their survival and adaptability. Understanding bacterial behavior is crucial for fields like medicine and environmental science.
