Benefits:
In a lab, scientists can control the conditions according to their research and study. This allows them to focus on a single perspective.

Drawbacks:
Ina laboratory experiment, we cannot control every variable which might be having an effect on our concerned subject as compared to a natural setting. This is because lab experiments are performed in a controlled experiment. Hence, there might be difference of results in a lab experiment and nature.
