Butler Biology Unit 14

Front 1

Microorganisms

Back 1

Living things which are not visible without use of a microscope

Front 2

Lytic Cycle

Back 2

Describes the “life cycle” in which a virus quickly kills the host cell

Front 3

Lysogenic Cycle

Back 3

Describes the “life cycle” in which the virus has a dormant (inactive) stage

Front 4

Malaria

Back 4

A disease caused by parasitic protists called plasmodia - transmitted by a mosquito

Front 5

Antigen

Back 5

The term used to describe a foreign invader, such as a virus, bacteria, or pollen

Front 6

Viruses

Back 6

Composed of a protein coat (called a capsid) that protects a nucleic acid (may be either DNA or RNA). Viruses are not cellular because they lack a cell membrane, cytoplasm, and ribosomes

Front 7

Lysis

Back 7

The rupture of the cell

Front 8

Respiratory Cells

Back 8

Cells that line your throat and lungs

Front 9

Influenza

Back 9

Transmitted through droplets of affected bodily fluids, such as saliva and mucus. The virus survives long enough outside the host organism that droplets left on surfaces (such as a desk) contain viable viral particles for several hours

Front 10

Smallpox

Back 10

Transmitted by droplets exhaled by infected people. Virus can survive prolonged periods of time in dust, clothing, bedding and other objects

Front 11

Vector

Back 11

Any organism which transmits/carries a disease without being affected by the disease

Front 12

Active Immunity

Back 12

Develops when a person is exposed to microorganisms or foreign substances and the immune system responds

Front 13

Passive Immunity

Back 13

Acquired when antibodies are transferred from one person to another. This may happen from mother to child (across the placenta or through breast milk) or from a serum containing pre-formed antibodies (ex. antivenom)

Front 14

Antibiotics

Back 14

Ddestroy bacteria by creating holes in the bacteria cell wall or preventing protein synthesis within the bacteria cell (effectively shutting down the cell)

Front 15

Antiviral Medicines

Back 15

Interfere with the life cycle of the virus, stopping further damage

Front 16

Anti-fungal Medicines

Back 16

Destroy the fungal cells causing the diseases
