Why might a scientist prefer to use the lower powers of a light microscope to observe aspects of unicellular organism?

Using lower powers on a light microscope allows for a wider field of view, which can be useful for observing larger structures or movements such as cell motility. It can also provide better depth of field, making it easier to focus on different layers of the organism. Additionally, lower powers can help preserve the specimen by minimizing the intensity and duration of light exposure.
