Unit 9 Classification Of Organisms: Bacteria, Protista, Fungi Vocabulary

Front 1

Binary Fission

Back 1

When a bacteria has grown to double its size, it replicates its DNA and divides in half into daughter cells. Asexual reproduction.

Front 2

Protista

Back 2

An organism that is not a plant, animal, or fungus.

Front 3

Spore

Back 3

A haploid reproductive cell that is capable of growing into a new individual without fusing with another cell.

Front 4

Symbiosis

Back 4

A relationship where two species live close together.

Front 5

Mutualism

Back 5

A relationship between two organisms that live close together in which both organisms are benefited in some way.

Front 6

Commensalism

Back 6

A relationship between two organisms that live close together in which one organism is benefited while the other is unaffected.

Front 7

Parasitism

Back 7

A relationship between two organisms that live close together in which one organism is harmed and the other is benefited.

Front 8

Louis Pasteur

Back 8

The scientist who disproved spontaneous generation by showing that broth that was boiled and left in a flask did not spontaneously grow.

Front 9

Germ Theory of Disease

Back 9

1. The pathogen should always be found in a sick organism and never in a healthy one.

2.The pathogen must be isolated and grown in a lab culture.

3.When the culture pathogen is placed in a new host, it should cause the same disease that infected the original host.

4.The pathogen should be recovered from the second host, and should be identical to the original pathogen.

Front 10

Viruses

Back 10

Particles of nucleic acids surrounded by a protein coat, and sometimes lipids form the host cell.

Front 11

Capsid

Back 11

A protein coat.

Front 12

Bacteriophages

Back 12

Viruses that infect bacteria.

Front 13

Lytic Infection

Back 13

When the virus enters a cell, makes copies of itself, causing the cell to burst.

Front 14

Lysogenic Infection

Back 14

When a virus integrates its DNA into the DNA of the host cell, and the viral genetic information replicates along with the host's cell DNA indefinitely. At some point the virus activates and goes into a lytic cycle.

Front 15

Taxonomy

Back 15

The discipline of classifying organisms and assigning names.

Front 16

Taxon

Back 16

Each level of categorization.

Front 17

Monera

Back 17

The kingdom for bacteria.

Front 18

Phylogeny

Back 18

The study of evolutionary descent, not just what they look like.

Front 19

Cladogram

Back 19

Model used to represent the evolutionary history of an organism.

Front 20

Domain

Back 20

Larger grouping system than kingdom.

Front 21

Eukarya

Back 21

Includes potist, fungi, plant, and animal kingdoms.

Front 22

Bacteria

Back 22

Includes the eubacteria kingdom.

Front 23

Archaea

Back 23

Includes the archaea bacteria kingdom
