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 ...
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 ...
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 structures at the cell plasma membrane, where secretory vesicles transiently dock and fuse to ...
The pressure flow hypothesis, also known as the mass flow hypothesis, is the best-supported theory to explain the movement of sap through the phloem of plants. [1][2] It was proposed in 1930 by Ernst Münch, a German plant physiologist. [3] Organic molecules such as sugars, amino acids, certain hormones, and messenger RNAs are known to be ...
Wholesale marketing of food. In the fruits and vegetables sector of the Rungis International Market, France. The consumption and production of marketed food are spatially separated. Production is primarily in rural areas while consumption is mainly in urban areas. Agricultural marketing is the process that overcomes this separation, allowing ...
Bulk foods are food items offered in large quantities, which can be purchased in large, bulk lots or transferred from a bulk container into a smaller container for purchase. [1] Bulk foods may be priced less compared to packaged foods because they are typically packaged in large generic bulk containers and packaging for grocery outlets, which ...
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.
