How unicellular react danger?

Unicellular organisms respond to danger through various mechanisms, such as the detection of harmful stimuli or environmental changes. They may alter their behavior by moving away from toxins or predators, often using flagella or cilia for locomotion. Some unicellular organisms, like bacteria, can enter a dormant state or form spores to survive adverse conditions. Additionally, they may release chemical signals to communicate with other cells or initiate defense mechanisms.
