Answer
The coverslip serves several purposes: it prevents the sample from drying out, keeps the specimen flat to enhance clarity, and protects the sample from contamination. Additionally, it prevents damage to the lens of the microscope by maintaining an appropriate distance between the lens and the specimen.
