Answer:
Field research and laboratory research are different from each other on various accounts. In a lab, the study is not on such a broader level as that on a field.
Some of the tools in a lab and a field study will be same because such tools cannot be changed. For example, for amplification of genes, PCR will be used whether a field research is being made or a lab research.
On the other hand, some of the tools will be different. For example, to study field plants we'll use quadrants for counting but in a lab, as a lesser number of plants are understudy so we won't need a quadrant.
