Mass flow (life sciences) In the life sciences, mass flow, also known as mass transfer and bulk flow, is the movement of fluids down a pressure or temperature gradient. [1] As such, mass flow is a subject of study in both fluid dynamics and biology. Examples of mass flow include blood circulation and transport of water in vascular plant tissues.
Bulk movement. In cell biology, bulk flow is the process by which proteins with a sorting signal [definition needed] travel to and from different cellular compartments. In other words, bulk transport is a type of transport which involves the transport of large amount of substance like lipid droplets and solid food particles across plasma ...

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 ...
Exocytosis ( / ˌɛksoʊsaɪˈtoʊsɪs / [1] [2]) is a form of active transport and bulk transport in which a cell transports molecules (e.g., neurotransmitters and proteins) out of the cell ( exo- + cytosis ). As an active transport mechanism, exocytosis requires the use of energy to transport material. Exocytosis and its counterpart ...
Bulk purchasing or mass buying is the purchase of much larger quantities than the usual, for a unit price that is lower than the usual. Wholesaling is selling goods in large quantities at a low unit price to retail merchants. The wholesaler will accept a slightly lower sales price for each unit, if the retailer will agree to purchase a much ...
A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials that are feedstock for future finished products. As feedstock, the term connotes these materials are bottleneck assets and are required to produce other products.
Bulk material handling is an engineering field that is centered on the design of equipment used for the handling of dry materials. Bulk materials are those dry materials which are powdery, granular or lumpy in nature, and are stored in heaps. [1] Examples of bulk materials are minerals, ores, coal, cereals, woodchips, sand, gravel, clay, cement ...
