Biodiversity And Classification Of microorganisms Flashcards
Karyote
Nucleus
Obligate intracellular parasite
Can only survive inside cells of living organisms
Extremophile
Lover of extremes
Peptidoglycan
Mixture of polysaccharide and amino acids
Flagella
Tendril-like outgrowths
Cilia
Hair-like structures
Sessile
Fixed to one point
Dinoflagellates
2 flagella bacteria
Protozoan
First animal
Pseudopodia
False feet
Plankton
Numerous microorganisms floating in currents of the open ocean
Taxonomist
A person who classifies organisms into groups based on shared features
Extracellular digestion
Use digestive enzymes to break down organic matter into a form they can absorb
Saprotrophic
Feeding on dead organisms and decaying organic matter
Hyphae
Mass of branched filaments enclosed by a rigid cell wall
Detritivores
An organism that uses organic waste as a food source (e.g. Some insects)
Human flora
Microorganisms (bacteria/ fungi) that live in the human body
- some useful
- majority = no beneficial effect/ harm
Viral load
Amount of HIV in a person’s blood
Cultivar
Plant variety produced by breeding
Virulent
Actively poisonous
Vector
Animal that carries a pathogen
Necrotic
Dying
MDR-TB
Organism resistant to 2 first line drugs
XDR-TB
Extremely drug resistant
- resistant to 3 or more 2nd line treatment drugs
Debilitating
To make weak or feeble
Anaemia
Destruction of red blood cells
ITN
Insect treated nets
Haustoria
Root-like structures
Topical
Applied directly to body’s surface
Keratin
Dead outermost layer of skin
Antigen
A protein/ layer polysaccharide molecule in the coat of a virus or a bacterium which causes B lymphocytes to make antibodies
Antibody
A protein made by B lymphocytes that destroys or neutralizes a germ
Phagocyte
Cell that eats
Phagocytosis
Phagocyte surrounds germ when in contact
- phagocyte engulfs pathogen
Vaccination (immunization)
The process of giving a vaccine to a person by injection or orally, to make them immune to a disease
Vaccine
Suspension of dead, weakened or fragmented microorganisms, or their toxins, that will stimulate the production of antibodies by the B lymphocytes (antibody cells), which will cause immunity.
Artificially acquired immunity
Uses vaccination
- most antibodies stay in blood giving long-lasting protection against the disease
Drug
Chemical substance used in treatment, cure or prevention of a disease/ disorder.
Antibiotic
Drugs that fight infections caused by bacteria
Super bug
Bacteria resistant to almost all known antibiotics
