Virus |
A virus is a biological cell that reproduces inside the cells of living hosts. When infected by a virus, a host cell is forced to produce many thousands of identical copies of the original virus, at a really big rate. It is bad! |
|
Vaccine |
A biological preparation that provides active acquired immunity to a particular disease, like smallpox. |
|
Anti-Viral |
Antiviral drugs are a class of medication used specifically for treating viral infections. |
|
Bacteria |
A member of a large group of unicellular microorganisms that have cell walls but do not have organelles and an organized nucleus, including some that can cause disease. Some can help though. |
|
Parasite |
An organism that lives in or on another organism (its host) and benefits by taking nutrients at the host's expense, usually death. |
|
Prokaryote |
A microscopic single-celled organism that has no nucleus with a membrane or other organelles. Prokaryotes include the bacteria and cyanobacteria. |
|
Eukaryote |
An organism consisting of a cell in which the genetic material is DNA in the form of chromosomes in a nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria. They have organelles too. |
|
Protist |
Microscopic organisms containing a nucleus or nuclei that hold their genetic material,and accordingly are categorized as eukaryotic. |
|
Epidemic |
An epidemic is an outbreak of a disease that affects an unusually large number of individuals within a population, community, orregion compared to recent memory. It does not affect individuals worldwide. |
|
Pandemic |
A pandemic is an epidemic of infectious disease that has spread over an entire continent, multiple continents, or even worldwide. It is always contagious. |
|
Vector |
A disease vector is any organism that can spread infectious disease to another organism through bites, scratches, body fluids, orother contact. |
|
Fungi |
Any of a group of unicellular, multicellular, or (eukaryotic) organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools. |
|
Protein Coat |
A structure composed of proteins that holds the nucliec acid of a virus. Also called a capsid. |
|
Tail Fiber |
Some viruses have it. It is a long leg used for the attachment to the host cell. |
|
Flagella |
A whip-like structure that helps the eukaryote move. |
|
Cilia |
Hair-like form of movement that helps to draw food in to the mouth lined with more cilia. |
|
Mitosis |
A process that creates identical cells for repair and growth in the human body. |
|
Meiosis |
A process that creates sperm and egg cells in the human body. |
|
Binary Fission |
A kind of asexual reproduction. It is the most common form of reproduction in prokaryotes and occurs in some single-celled eukaryotes. It is commonly called division in half. |
|
Virion |
The infectious form of a virus. |
