Discovered the association between hand washing and a decrease in puerperal infection (1850)

6

Louis Pasteur

Disproved the theory of spontaneous generation and develops the germ theory of infection (1861)

Developed rabies vaccine (1885)

7

Joseph Lister

First to practice surgery using antiseptic practices (1867)

8

Robert Koch

Offers the first proof of the germ theory using Bacillus anthracis (1876)

14

In a prokaryotic cell, the DNA is:

Loose in the cytoplasm

15

In a eukaryotic cell, the DNA is:

Enclosed in a nuclear membrane

16

Virology is:

The study of viruses

17

Bacteriology is:

The study of bacteria

18

Parasitology is:

The study of parasites

19

Pathology is:

The study of disease mechanisms

20

Epidemiology is:

The study of disease or an event pattern

21

Microorganisms, or microbes, are:

Life forms that are too small to be seen with the naked eye

Found inside and outside the human body

22

Cell Theory states that the cell is:

The fundamental unit of all living things

23

Prokaryotic Cells

Cellular organisms that lack a true nucleus

DNA is loose in the cytoplasm

Surrounded by a cell membrane

24

Eukaryotic Cells

DNA enclosed in a nuclear membrane

Surrounded by a double-layered membrane

Pinocytosis is:

Cell Drinking

34

Phagocytosis is:

Cell eating

35

Isotonic means:

The concentration of is equal on both the inside and outside of the cell membrane

36

Hypertonic means:

The concentration is greater outside than inside the cell membrane

37

Hypotonic means:

The concentration is lower outside the cell membrane then than inside

38

Osmosis is:

The passing of molecules through a membrane from high to low concentration

Passive Transport

39

Diffusion is:

Simple movement of particles in a solution, high concentration to low concentration

Passive Transport

40

The nucleus is:

The control center of the cell

False

42

T/F:

The smooth endoplasmic reticulum does NOT have ribosomes

True

43

The golgi complex is responsible for:

Packing proteins

44

A lysosome contains:

Enzymes that destroy foreign substances that were ingested by the cell

45

The mitochondria is:

The powerhouse of the cell

46

The centrioles are spindle fibers that aid in:

Cell division

47

Endotoxins are:

Poisons contained in some gram negative microorganisms

*Strong enough to get into the blood stream

48

Exotoxins are:

Toxins released by living bacterial cells into its surroundings

49

Hyaluronidase hydrolyzes this protein allowing microorganisms to spread:

Hyaluronic Acid
