Stomata
A microscopic pore surrounded by guard cells in the epidermis of leaves and stems that allows gas exchange between the environment and the interior of the plant.
Protist
Protists are the members of an informal grouping of diverse eukaryotic organisms that are not animals, plants or fungi. They do not form a natural group, or clade, but are often grouped together for convenience, like algae or invertebrates.
Tm
At the melting temperature half of the oligo will form duplex with complementary oligo at the same concentration. PCR annealing temperature is usually set a few degrees lower than the melting temperature.
Domain
The highest level of biological classification which goes beyond kingdoms. The three domains of biological organisms are Bacteria, Eukarya, and Archaea.
Fossil
Fossil is any preserved evidence of life from a past geological age, such as the impressions and remains of organisms embedded in stratified rocks.

Protonephridium
An excretory system, such as the flame-cell system of flatworms, consisting of a network of closed tubules having external openings called nephridiopores and lacking internal openings.
Antimicrobial Resistance
Antimicrobial resistance threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi.
Repression
Process by which an enzyme synthesis is suppressed due to the presence of certain external substance.
Artificially Acquired Passive Immunity
Artificially acquired passive immunity is a short- term immunization achieved by the transfer of antibodies.
Age Structure
The relative number of individuals of each age in a population.
Oligosaccharide
Oligosaccharide is a carbohydrate polymers comprise three to ten monosaccharides, or, simple sugars.
They were linked together mostly by O-glycosidic bond through condensation reaction between an anomeric carbon of a monosaccharide and the other.
Biotin
Biotin, is a water-soluble B-vitamin, formerly known as vitamin H or coenzyme R. It is composed of a ureido ring fused with a tetrahydrothiophene ring.
Cline
In biology and ecology, a cline describes an ecotone in which a series of biocommunities display a continuous gradient.
Artificially Acquired Passive Immunity
Artificially acquired passive immunity is a short- term immunization achieved by the transfer of antibodies.
