Microbe |
The tiny living thing that can not be seen with out microscopic |
|
Virus |
Is an infectious particle that reproduce by commandeering a host cell and using its machinery to make more virus. Tiny, non living particle that invade and then reproduce inside a living cell |
|
Pathogen |
Any disease- producing agent ( specially a virus or bacterium or other microorganism ) |
|
Pandemic |
An epidemic that is geographically widespread |
|
Prokaryotic cell |
A cell that lack a nucleus and other membrane bound organelles; include Achaea and bacteria |
|
Eukaryotic cell |
A cell containing a nucleus and other membrane bound organelles |
|
Mycelium |
A cluster of interwoven mass of hyphae aids the fungus in eating and reproduction |
|
Motility |
Is the ability of an organism to move by itself Seen only in eukaryotic organism Done only in multicellular organisms |
|
Nucleoid |
Is the region of the a prokaryotic cell that houses the primary DNA. This lesson briefly discusses the nucleoid and its characteristic and how it compares to the nucleus of the eukaryotic cell |
|
Plasmid |
A small, circular, double stranded DNA molecule, which can replicate independently from its chromosomal DNA. If plasmids are used for experiments, they are called vector |
|
Transformation |
Naked DNA uptake by bacteria |
|
Horizontal gene transfer |
The transfer of gene from one genome to another through mechanism such as transposable elements, plasmid exchange, virtual activity, and perhaps, fission of different organisms |
|
Horizontal gene transfer |
The transfer of genes from one genome to another through mechanism such as transposable elements, plasmid exchange, viral activity, and perhaps, fission of different organism |
|
Transformation |
A movement of a figure in a plane from its original position, the pre-image, to a new position, the image |
|
Mycorrhizae |
Special symbiotic relationship between fungus and plant root. Plant provides fungus with organic molecules; Fungus provides plant with greater access to reliable source of inorganic nutrient |
|
Transduction |
the process of using a bacteriophage to move pieces of chromosomal DNA from one bacterial cell to another |
|
F factor |
A fertility factor in bacteria; A DNA segment that confers the ability to form pili for conjugation and associated functions required for the transfer of DNA from donor to recipient. It may exist as a plasmid or be integrated into the bacterial chromosome |
|
Hfr cell |
A cell with the F plasmid integrates into the chromosome |
|
Lichen |
Is a fungus that consists of two or more species of organism that live together with photosynthesis partner. The fungus is the shelter or protector of the grouping, while the photosynthetic partners provide the food |
|
Antibiotic resistance |
Ability of bacteria or other microbes to resist the effects of an antibiotic |
|
Bioremediation |
Is the process of cleaning up environmental sites contaminated with chemical pollutants by using living organisms to degrade hazardous material into less toxic ones |
|
Phototroph |
The process that converts solar energy into chemical energy |
|
Chemotroph |
Can not photosynthesize Obtain their energy from other resource |
|
Autotroph |
An organism that is able to capture energy from sunlight or chemicals and use it to produces its own food |
|
Heterotrophs |
An organism that can not make its own food and gets its food by consuming other living things |
|
Obligate aerobic |
An organism that requires oxygen to grow. Through cellular respiration, there organism use oxygen to metabolize substance, like sugar or fats, to obtain energy |
|
Obligated anaerobic |
Are microorganisms that are killed by normal atmospheric concentrations of oxygen |
|
Spore |
can form within vegetative cells and can cause spoilage of high acid foods |
|
Aerobic respiration |
Process that occurs mostly in the mitochondrion that requires oxygen gas, consumes sugar and produces ATP, every efficient |
|
Anaerobic respiration |
Occurs in cytosol, no oxygen present, makes ATP, much less efficient |
|
Facultative anaerobic |
Organisms that can produce energy via a robin respiration using oxygen as the final electron acceptor, or in the absence of oxygen, can perform fermentation or anaerobic respiration, which uses something besides oxygen as a final electron acceptor such as sulfate |
|
Nitro fixation |
Process by which N2 is reduced to NH3 by nitrogen and then converted to cellular material |
|
Parasitism |
A relationship in which one kind of organism lives on or in another organism and may harm |
|
Mutualism |
A relationship in which both plants/ animal benefit |
|
Commensalism |
A relationship between 2 plants/ animals in which one benefits and the other is uncharged |
|
Gram-negative bacteria |
stain is pink, thin peptidoglycan 3 layers in cell envelope -Inner membrane ( lipid bilateral) - thin peptidoglycan layer - outer membrane |
|
Gram- positive bacteria |
Bacteria that retains purple stain inside the wall during the gram staining procedure, it has the thick peptidoglycan layer, purple positive protein |
