You are going to participate in a national academic competition. This competition involves a simulated game called Bacteria War. You are required to design a new bacteria cell which exhibits the highest infection capacity.

a) Draw and label the significant structural features of the new bacteria cell : cell shape, cell wall, one additional cytoplasmic structure.

b) What microscopy techniques are employed to examine bacterial samples and distinguish between morphological characteristics like Gram-positive and Gram-negative? Additionally, provide a brief overview of the selected method's procedural steps.

c) When you are using the microscope, your lab partner suggests the resolution of the microscope and refraction of light should be aware of. Distinguish between resolution and refraction.
