In the Gram stain, gram-positive bacteria are dark purple for all the following reasons EXCEPT: The primary stain, crystal violet, is dark purple The counterstain (safranin) causes the purple color to develop Thick peptidoglycan in the gram-positive cell wall prevents decolorization by alcohol Crystal violet is fixed inside the cell as a CV-Iodine complex once iodine is added None of the other four answers (All are reasons that gram-positive bacteria are purple
Bacterial Morphology
The bacteria are prokaryotic organisms that are single-celled, and are found to exist as free-living and possess a microscopic size. The morphology is found to vary in the bacteria, where some of them are identified as individual organisms and the others are detected as colonies. The size and shape of the bacterial cell also represent its morphology.
Bacterial cell structure
Bacteria are single-celled, tiny creatures that may enter healthy tissues and grow rapidly. Bacteria are microscopic organisms that are tiny and unicellular. These are members of the prokaryote kingdom. They live in water, air, soil, and all-natural environments. They are used in industrial and therapeutic processes, and they support a wide range of plant and animal life. The first organism to appear on the planet. Bacteria-like creatures are the oldest known fossils. Bacteria can consume a wide range of organic and inorganic elements, and some may even survive in harsh conditions.
