CLINICAL MEDICINE

Detailed explanation-1: -Fungi (pronounced: FUN-guy) are multicelled, plant-like organisms. A fungus gets nutrition from plants, food, and animals in damp, warm environments. Many fungal infections, such as athlete’s foot and yeast infections, are not dangerous in a healthy person.

Detailed explanation-2: -Protozoa Protozoa are single-cell organisms that are attracted to moisture, and therefore spread disease through water. Oftentimes protozoa are the source of intestinal infections that cause nausea, pain and diarrhea.

Detailed explanation-3: -A protist is a one-or many-celled organism that lives in moist or wet surroundings. Unlike bacteria, protists’ cells are eukaryotic.

Detailed explanation-4: -Microorganisms can be unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). They include bacteria, archaea, fungi, protozoa, algae, and viruses. Bacteria are single celled microbes that lack a nucleus. Archaea are like bacteria, but they have different structures and properties.

Detailed explanation-5: -Bacteria are microscopic, single-celled organisms that exist in their millions, in every environment, both inside and outside other organisms. Some bacteria are harmful, but most serve a useful purpose. They support many forms of life, both plant and animal, and they are used in industrial and medicinal processes.
