Some protists are able to live in air by possessing various adaptations that allow them to survive in this environment. For example, some protists have a protective coat of mucilage or a thick cell wall that prevents desiccation, or drying out, in the air. Others have developed the ability to move quickly, such as through the use of flagella or cilia, which allows them to move away from adverse conditions. Additionally, some protists are able to form spores, which are resistant structures that can survive in harsh environments, including in the air. These spores can later germinate and develop into new individuals when conditions become more favorable.
I hope this helps :)
