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.

![Below are the results of our disc diffusion study using antiseptics and disinfectants. Use the results to answer the following questions:
| | 1:10 diluted bleach (BL) | Lab Disinfectant (DIS) | Isopropanol (ISP) | Lab soap (SO) | Lysol (LYS) | Tincture of iodine (T of I) |

Explanation:
The table summarizes the results of a disc diffusion experiment assessing the effectiveness of various chemicals against two types of bacteria, _E. coli_ (a Gram-negative bacterium) and _Bacillus cereus_ (a Gram-positive bacterium). The measurements, recorded in millimeters, indicate the diameter of the inhibition zones around each chemical, reflecting its effectiveness. Larger numbers signify greater antibacterial activity.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe24735fd-3291-4647-b61f-a148a3463e38%2F681c04ad-0bdf-498e-baa6-595138b2518b%2Fl3sqa4i_processed.jpeg&w=3840&q=75)
