    A bacterial colony grows from a single bacterial cell. The colony consists of millions of bacterial cells and is visible to the human eye. The student will observe that each colony has a characteristic shape, size, texture, and color.

    Procedure

    Obtain agar plates prepared in section 14.3. Leave the covers on. Observe the colonies by eye and under the dissecting microscope. Complete data table
