DOH133 Lecture Notes - Lecture 8: Fluorophore, Refraction, Green Fluorescent Protein
List the three domains of life
1. Bacteria
2. Archaea
3. Eukarya
Some key contributors to microbiology history
- Ancestors of archaea & bacteria were the first life on Earth
- 1665 Robert Hooke coined the term “Cells” to describe the box-like
structures he saw in cork tissue. They reminded him of monks small rooms
– cells. This marked the beginning of the cell theory – that all living things
are composed of cells
- 1673 Anton van Leeuwenhoek observed the first microbes. He was a
Dutch clothes merchant. Now considered to be a genius. He originally
made microscopes to look at cloth fibres but ended up looking at things
like his teeth scrapings, his faeces and pondwater
- He was the first to see bacteria and protozoa which he called “animalcules”
(little animals)
Compare spontaneous generation and biogenesis
1. Spontaneous generation: The hypothesis that living organisms arise from
nonliving matter; a “vital force” forms life
2. Biogenesis: The hypothesis that the living organisms arise from preexisting
life
Word definitions related to the study of microbiology
- Bacteriology is the study of bacteria
- Mycology is the study of fungi
- Parasitology is the study of protozoa and parasitic worms
- Virology is the study of viruses
- Immunology is the study of immunity
- Toejamology is the study of fungal foot infections
List the SI units of length and their abbreviations
10-3 m = 1 mm
10-6 m = 1 µm (micro metre)
10-9 m = 1 nm (nano metre)
1000 nm = 1 µm
Document Summary
List the three domains of life: bacteria, archaea, eukarya. Ancestors of archaea & bacteria were the first life on earth. 1665 robert hooke coined the term cells to describe the box-like structures he saw in cork tissue. This marked the beginning of the cell theory that all living things are composed of cells. 1673 anton van leeuwenhoek observed the first microbes. He originally made microscopes to look at cloth fibres but ended up looking at things like his teeth scrapings, his faeces and pondwater. He was the first to see bacteria and protozoa which he called animalcules (little animals) Compare spontaneous generation and biogenesis: spontaneous generation: the hypothesis that living organisms arise from nonliving matter; a vital force forms life, biogenesis: the hypothesis that the living organisms arise from preexisting life. Word definitions related to the study of microbiology. Parasitology is the study of protozoa and parasitic worms. Toejamology is the study of fungal foot infections.
