culture
Microorganisms that grow and multiply in a container of culture medium.
Cycloaddition reaction
A peri cyclic reaction in which two reactants add together in a single step to yield a cyclic product. The Diels–Alder reaction between a diene and a dienophile to give a cyclohexene is an example.

Ecosystem services
The advantages for humans obtained from ecosystems.
Elution
The passage of a substance from a chromatography column.
