Bulk flow in plants
WebIn amphibians, reptiles, birds, and mammals, blood flow is directed in two circuits: one through the lungs and back to the heart, which is called pulmonary circulation, and the other throughout the rest of the body and its organs including the brain (systemic circulation). WebBulk flow functions in long-distance transport. Diffusion in a solution is fairly efficient for transport over distances of cellular dimensions (less than 100 microns). However, diffusion is much too slow for long-distance transport within a plant, such as the movement of water and minerals from roots to leaves.

WebWhich of the following statements about bulk flow are correct? I) Bulk flow is driven primarily by pressure potential. II) Bulk flow depends on a difference in pressure potential at the source and sink. III) Bulk flow depends on the force of gravity on a column of water. WebA) upper leaf surface of a single plant divided by the surface area of the land on which the plant grows B) lower leaf surface of a single plant divided by the surface area of the land on which the plant grows C) upper leaf surface of a single plant multiplied by the surface area of the land on which the plant grows
http://pressbooks-dev.oer.hawaii.edu/biology/chapter/transport-of-water-and-solutes-in-plants/ WebBulk flow allows key molecules to be transported over distances much greater than those possible that can be covered by diffusion alone, making larger organisms possible. Other organisms, such as sponges or jellyfish, grow large by adopting shapes and structures that allow metabolically active cells to remain in close proximity to the environment.
