NEET BIOLOGY

Detailed explanation-1: -Mass flow, also known as mass transfer and bulk flow, is the movement of fluids down a pressure or temperature gradient, particularly in the life sciences. As such, mass flow is a subject of study in both fluid dynamics and biology.

Detailed explanation-2: -Mass flow or bulk flow is the movement down a pressure gradient ( a pressure gradient in plants is observed due to variations in solute concentration) or temperature gradient of substances in bulk or in masses. Xylem and phloem in plants play a similar role as veins and arteries in animals.

Detailed explanation-3: -Water, minerals, and food in plants generally move by a mass or bulk flow system. Mass flow is the movement of substances in bulk from one point to another as a result of pressure differences between the two points.

Detailed explanation-4: -Solution : Mass flow is the movement of substances in bulk or en masse from one point to another as a result of pressure difference between the two points.
