Term | Definition |
---|---|
Antibody | A blood protein produced in response to and counteracting a specific antigen. |
Antigen | A toxin or other foreign substance that induces an immune response in the body |
DNA | A self-replicating material present in nearly all living organisms as the main constituent of chromosomes |
Host cell | An animal or plant on or in which a parasite or commensal organism lives |
Lymphocyte | A form of small leukocyte with a single round nucleus, occurring especially in the lymphatic system |
Lytic cycle | The lytic cycle results in the destruction of the infected cell and its membrane. |
Membranous envelope | A double layer of lipid, containing some proteins, that surrounds biological cells and some of their internal structures |
Mucous membrane | An epithelial tissue that secretes mucus and that lines many body cavities and tubular organs including the gut and respiratory passages |
Nucleic acid core | Any of the group of complex compounds consisting of linear chains of monomeric nucleotides |
Phagocytic white blood cells | Phagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells. |
Primary Line of defence | Physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, ‘friendly’ bacteria and white blood cells called neutrophils. |
Protein Capsid | A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers |
RNA | ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins |
Secondary Line of Defence | The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system. |
Tertiary line of defence | Tertiary line of defence are the antibodies |
Viral specificity | Viral specificity means that a virus is selective in the organisms it infects, the type of cells and the disease it produces |
White Blood cell | One of the cells the body makes to help fight infections. |
Aerobic Respiration | the release of energy from glucose or another organic substrate in the presence of Oxygen. |
Antibiotic | a medicine that inhibits the growth of or destroys microorganisms. |
Antiseptic | Denoting substances that prevent the growth of disease-causing microorganisms. |
Bacteria | member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease. |
Binary fission | asexual reproduction. |
Classification | the action or process of classifying something according to shared qualities or characteristics. |
Conjugation | The process whereby two ciliates come together in a temporary fusion to exchange micronuclear material, then separate, each being a fertilized cell |
Disinfectant | A chemical liquid that destroys bacteria. |
Ecological Role | ecological niche definition. The place or function of a given organism within its ecosystem. Note: Different organisms may compete for the same niche. For example, in a forest there may be a niche for an organism that can fly and eat nectar from blossoms. |
Fermentation | the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat. |
Motility | motility is the ability to move spontaneously and actively, consuming energy in the process. |
Mutation | the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations |
Photosynthesis | the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. |
Prokaryote | A microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. |
Resistant | The natural or genetic ability of an organism to avoid or repel attack by biotic agents |
