Active transport: The movement of particles against the concentration gradient into or out of a cell. Bulk transport:The movement of large molecules into or out of the cell. Both of these require energy
Diffusion in fluid occurs when particles move from an area of high concentration to an area of low concentration due to random motion. Convection, on the other hand, involves the bulk movement of fluid resulting from temperature or density differences. In a fluid, both diffusion and convection can occur simultaneously, with diffusion driving molecular movement within the fluid while convection causes bulk movement of the fluid itself.
Bulk conveying systems enable the movement and handling of a large amount of products or items. Bulk conveying should allow companies to run more efficient operations.

The difference between the two is that bulk motion is the flow through the capillary. Diffusion is the movement of the molecules in a fluid.Ê
Bulk transport in cells is the movement of large quantities of molecules or particles across the cell membrane at once. This process helps in the efficient transport of substances such as proteins, polysaccharides, or even entire organelles. Bulk transport includes both endocytosis (taking in substances) and exocytosis (releasing substances).
Heat transfer within a fluid occurs through conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between molecules, convection is the movement of heat through the bulk movement of fluid particles, and radiation is the transfer of heat through electromagnetic waves. These mechanisms work together in the fluid to distribute heat energy and ensure thermal equilibrium.
Convection heat transfer occurs due to the bulk movement of fluid particles, such as air or water, which carry thermal energy from one place to another. As the fluid particles are heated, they become less dense and rise, while cooler particles sink. This movement sets up a current that transfers heat through the fluid.
The bulk liquid of a solution is called the solvent. It is the component that dissolves the solute in a solution. Water is a common solvent used in many solutions.
Allocating: Breaking a homogeneous supply into smaller and smaller lots ("breaking bulk")
Mass movement. Mass movement, also called Mass Wasting, bulk movements of soil and rock debris down slopes in response to the pull of gravity, or the rapid or gradual sinking of the Earth's ground surface in a predominantly vertical direction.
