182 points Which of these in INCORRECT? Store agar plates upside down to avoid condensation from obstructing growth. Use the same L-shaped spreader for each plate for experimental control. Label around the rim of the plate so you can see the bacterial growth clearly. Label the bottom of the agar plate so the label cannot be separated from the bacteria if the top is lost. Clear my selection

To determine which statement is incorrect, let's analyze each one: 1. **Store agar plates upside down to avoid condensation from obstructing growth.** - This is correct. Storing agar plates upside down helps prevent condensation from forming on the lid, which can then run down onto the surface of the plate and potentially contaminate the bacterial growth. 2. **Use the same L-shaped spreader for each plate for experimental control.** - This is also correct. Using the same L-shaped spreader ensures that the same amount of bacteria is spread on each plate, which is important for maintaining experimental control. 3. **Label around the rim of the plate so you can see the bacterial growth clearly.** - This is correct. Labeling around the rim of the plate makes it easier to identify the different bacterial growths on the plate without having to look at the bottom of the plate. 4. **Label the bottom of the agar plate so the label cannot be separated from the bacteria if the top is lost.** - This statement is incorrect. It is not necessary to label the bottom of the agar plate. The label should be placed on the top of the plate where it is visible and less likely to be lost or damaged. The bottom of the plate is not typically labeled because it is not visible and it is not necessary for identifying the bacteria. Therefore, the incorrect statement is: **Label the bottom of the agar plate so the label cannot be separated from the bacteria if the top is lost.**
