Potpurri
100

The sticky sugars that surround the bacterium's cell wall, protecting it and allowing it to adhere to surfaces

Capsule

100

A saprophyte feeds on this

Dead matter

100

This infectious agent must infect another cell to reproduce

Virus

100

Developed by a Danish physician in the 1800s, this staining technique is one of the ways biologists classify bacteria by cell wall and structure

Gram stain

200

Cause sore throat, these bacteria are composed of long chains of round cells

Strepococcus

200

Photoautotrophs such as cyanobacteria derive their energy from this

Sunlight

200

The cycle in which a virus's DNA is replicated alongside the host's DNA

Lysogenic cycle

200

This process allows a desirable trait such as antibiotic resistance to be shared with another bacterium

Conjugation

300

A bacterium's "outboard motor", this structure is composed of the filament, hook, and basal body

Flagellum

300

Binary fission is an example of this type of reproduction

Asexual
300

The cycle in which a virus hijacks the host cell's DNA replication system, makes copies of itself, and causes the cell to burst

Lytic cycle

300

A chemical secreted by a living organism that kills or reduces the spread of other organisms

Antibiotic

400

Formed when growing conditions become unfavorable, this internal wall protects a bacterium's DNA and ribosome until conditions improve

Endospore

400

Using bacteria to treat sewage or to remove oil from water in oil spills are examples of this process

Microbial remediation
400

First developed in the 1700s by Edward Jenner, this weakened version of a pathogen is used to stimulate the body's immune system to prevent disease

Vaccine

400

Name one currently serving Senator from the State of Tennessee
