Lipopolysaccharide is an important component of this structure which is found in Gram-negative bacteria.

What is the outer membrane?

100

Process in which a eukaryotic cell engulfs particulate material to bring it into the cell.

What is phagocytosis?

100

The fungal cell wall is composed largely of this substance

What is chitin?

100

Sequences of this nucleic acid are most commonly used to determine evolutionary relationships of prokaryotic organisms.

What is 16S ribosomal RNA?

100

Dutch draper who built the best microscopes of his time and was the first to see and describe bacteria and other microbes.

Who was Antony van Leeuwenhoek?
200

These numerous protein filaments on the surface of many bacteria play an important role in attachment.

What are fimbriae (or pili)?

200

The protein tubule that makes up an important component of the cytoskeleton and forms the spindle during mitosis.

What are microtubules?

200

Filaments found in large numbers on the surface of some protozoa that are responsible for swimming motility

What are cilia?

200

This domain contains all eukaryotic organisms

What is the Eucarya?
200

French scientist who made many important contributions to early microbiology. Helped develop germ theory, refuted spontaneous generation, developed methods to preserve wine, etc.

Who was Louis Pasteur?

300

This material forms a very thick wall layer in gram-positive bacteria and a very thin layer in gram-negative bacteria.

What is peptidoglycan?

300

The endosymbiosis theory states that chloroplasts in eukaryotic plants and algae evolved from this type of endosymbiont.

What is a cyanobacterium?

300

A type of fungus consisting of single cells that reproduce by budding or binary fission

What is a yeast?

300

Organisms that have peptidoglycan in their cell walls are found in this
domain.

What is the domain Bacteria?

300

German botanist who proved that fungi could cause diseases in plants

Anton deBary

400

Structure produced by some bacteria which can remain dormant for long periods and is extremely resistant to adverse environmental conditions

What is an endospore?

400

In a eukaryotic cell, proteins destined for export from the cell would probably be produced here.

What is the rough endoplasmic reticulum (rough ER)?

400

These eukaryotic microbes secrete digestive enzymes and absorb the digested food

What are fungi?

400

Members of this domain have cell membranes that differ in fundamental ways from the cell membranes of organisms in the other two domains.

What is the domain Archaea?

400

German physician who developed procedures for proving that a particular microorganism causes a specific disease.

Who was Robert Koch?

500

Surface layers of Archaeal cells are composed largely of this material.

What is protein or glycoprotein?

500

Organelle that contains a variety of digestive enzymes and participates in intracellular digestion

What is a lysosome?

500

Symbiotic relationship between fungi and algae (or cyanobacteria)

What is lichen?

500

As environmental conditions become more and more extreme, one would expect to find a greater proportion of organisms from this domain.

What is the domain Archaea?

500

Microbiologist who did pioneering work on bacterial evolution that led to the recognition of the three domains of life.
