i did a lab experiement and I do not know what was the control group.

I tested the rates of cellular respiration for:

Germinated, room temperature peas

Non-germinated, room temperature peas

Germinated, cool temperature peas

Which one is the control group and how do you figure it out (by the way, the germinated warm peas had the highest respiration rate while the non-germinated cool temperature had the lowest cellular respiration rate)

It depends on your hypothesis. If your hypothesis was that the germinated would....respiration rate, then your control group was the Non germinated group.

Control groups are always that which are not manipulated.

To determine the control group in your lab experiment, you should look for the group that represents the baseline or normal condition against which you can compare the other groups. In this case, since you have three groups, the control group would typically be the one that is most representative of the typical or expected behavior.

Based on the information you provided, the control group would be the "Non-germinated, room temperature peas." Here's how you can figure it out:

1. Identify the purpose of your experiment: In this case, you are trying to study the rates of cellular respiration in different conditions.

2. Look for a group that represents the typical or expected behavior: The purpose of a control group is to establish a baseline or normal condition to compare the experimental groups against. It should represent the conditions in which you would expect to see average or typical rates of cellular respiration.

3. Analyze the information you have: From the information you provided, you mentioned that the germinated warm peas had the highest respiration rate, while the non-germinated cool temperature peas had the lowest respiration rate. Comparing this to the other group you mentioned, the germinated room temperature peas, it is likely that the non-germinated, room temperature peas would represent the control group. This is because they are non-germinated (representing a typical condition) and kept at room temperature (a common environmental factor).

4. Confirm your hypothesis: To ensure the accuracy of your conclusion, make sure to double-check your experimental setup or any instructions provided. Look for indications that one group was intended to be the control or any further information that supports your deduction.

Remember, the control group is crucial in providing a reference point for comparison and to establish the effect or impact of the experimental conditions.
