Diversity Of Life Unit 3

Front 1

Virus

Back 1

infectious particle made only of a strand of either DNA or RNA surrounded by a protein coat.

Front 2

Pathogen

Back 2

any living organism or particle that can cause an infectious disease is called an infectious agent or pathogen.

Front 3

Capsid

Back 3

protein shell that surrounds a virus

Front 4

Bacteriophage

Back 4

virus that infects bacteria.

Front 5

Lytic infection

Back 5

infectious pathway of a virus in which host cells are destroyed.

Front 6

Vaccine

Back 6

substance that stimulates an immune response, producing acquired immunity without illness of infection.

Front 7

Retrovirus

Back 7

virus that contains RNA and uses the enzyme called reverse transcriptase to make a DNA copy.

Front 8

Bioremediation

Back 8

process by which humans use living things to break down pollutants.

Front 9

Toxin

Back 9

poison released by an organism

Front 10

antibiotic

Back 10

chemical that kills or slows the growth of bacteria

Front 11

mycorrhizae

Back 11

ecological relationship between the mycelium of a fungus and the roots of certain plants.

Front 12

lichen

Back 12

fungus that grows symbiotically with algae, resulting in a composite organism that grows on rocks or trees.

Front 13

plasmid

Back 13

circular piece of material found in bacteria that can replicate from the DNA of its own chromosome.

Front 14

flagellum

Back 14

whip-like structure outside a cell that is used for movement.

Front 15

cilia

Back 15

hairlike structures that help the organism swim and capture food.

Front 16

pseudopod

Back 16

temporary extension of cytoplasm and plasma membrane; it helps protozoa move and feed.

Front 17

hyphae

Back 17

forms body and mycelium of fungus.

Front 18

lysogenic infection

Back 18

a phage combines its DNA into the host cell
