Usage of the term is not consistent; some ...
The release of one species to control another (Carlton 2001). The management of weeds using introduced herbivores (often insects) as biological control agents (Booth et al. 2003). Biological invasion or bioinvasion. A broad term for both human-assisted introductions and natural range expansions (Carlton 2001).
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
The term “biocontainment” is used differently in facilities for the study of human pathogens versus those used for the study of agricultural pathogens. In agricultural facilities, the definition for “biocontainment” resembles that for “biosafety,” i.e., the safety practices and procedures used to prevent unintended infection of ...
Exocytosis is the process by which a large amount of molecules are released; thus it is a form of bulk transport. Exocytosis occurs via secretory portals at the cell plasma membrane called porosomes. Porosomes are permanent cup-shaped lipoprotein structure at the cell plasma membrane, where secretory vesicles transiently dock and fuse to ...
Species reintroduction is the deliberate release of a species into the wild, from captivity or other areas where the organism is capable of survival. [1] The goal of species reintroduction is to establish a healthy, genetically diverse, self-sustaining population to an area where it has been extirpated, or to augment an existing population. [2]
Photosynthesis is the main means by which plants, algae and many bacteria produce organic compounds and oxygen from carbon dioxide and water ( green arrow ). An autotroph is an organism that can convert abiotic sources of energy into energy stored in organic compounds, which can be used by other organisms. Autotrophs produce complex organic ...
Anatomical terminology. [ edit on Wikidata] Exosomes, ranging in size from 30 to 150 nanometers, [1] are membrane-bound extracellular vesicles (EVs) that are produced in the endosomal compartment of most eukaryotic cells. [2] [3] [4] In multicellular organisms, exosomes and other EVs are found in biological fluids including saliva, blood, urine ...
