**Step-by-Step Solution:** 1. **Understanding Gram Staining**: The classification of bacteria into Gram-positive and Gram-negative is based on their reaction to the Gram stain, a method developed by Christian Gram in 1884. This staining process helps differentiate bacteria based on the structure of their cell walls. 2. **Staining Process**: During the Gram staining procedure, bacteria are first stained with a crystal violet solution, which gives them a blue color. This is followed by treatment with iodine, which helps fix the dye. 3. **Washing and Decolorization**: After the iodine treatment, the bacteria are washed with water and then treated with an organic solvent like alcohol or acetone. This step is crucial as it determines whether the bacteria will retain the blue color or not. ...
