Archaea?

prokaryotic

What cell type do all creatures besides Bacteria

and Archaea have?

eukaryotic

Define the term species and explain why

a mule is not an example of a species?

A species is a collection of individuals capable of successfully interbreeding

and producing fertile offspring. A mule is not capable of reproducing

What are the three main shapes of bacteria cells and the three main living arrangements of

bacteria?

Cocci Round Diplo Pairs

Bacilli Rod Staphxlo Cluster

After Gram staining what color do Gram

What are four main features used to

identify bacteria species?

ShapeCell wall structure

Food sourceRNA sequences

Why can’t bacteria reproduce sexually?

They lack a true nuclei

What happens basically when bacteria reproduce by conjugation? How many bacteria does conjugation start with and how many does conjugation end with?

More than one cell may be created – part or all of the genetic material is transferred to a cell the cell then

divides by binary fission creating more cells

What basically happens when bacteria

reproduce asexually

Binary fission – genetic material is reproduced (copied) and the cell

divides into two

What is an endospore? When would a capable bacteria create an endospore?

It is a seed like structure containing DNA – it is dormant and is produced during unfavorable conditions- will

come to life during favorable conditions

What is the name of the “jello” like

material used to grow bacteria on?

agar

What geometric shape do bacteria colonies

grow in?

Diplo pairs

Staphlo – clusters

Strepto - chains

What are antibiotics? What creatures can

antibiotics kill?  

Agents that can work to prevent bacteria from growing. They kill

bacteria.

What is antibiotic resistance? How does antibiotic resistance occur? 

Changes that make antibiotics ineffective. Genetic mutations

give rise to antibiotic resistance.

Relate the story of the accidental discovery of antibiotics.

Alexander Flemming – working an a bacteria noticed that a penecillin mould prevented the

bacteria from growingPenicillin notatum – bacteria staphyloccus

Principle of limited sloppiness

What are some of the extreme environments that members of the Kingdom Archaea live in?

Hot springsAlkaline/acidic waters

VolcanoesHot coal

Rock deep in the earth

Name three differences and two similarities between Kingdom Bacteria and Kingdom

Archaea?

Cell wall different structures

Cell wall different chemical composition

Different genes

Both move via flagella

Both have 3 shapes

Where do the following types of Archaea live and what do they do (See text page 138)?

 Methanogens 

Halophil Thermoacidophiles

Methanogens – methane producing – oxygen free environmentSalt loving – extremely saline environments

Heat/ acid loving – extremely hot and acidic environments
