Question

Assertion-Mass or bulk flow is the movement of substances in bulk from source to sink as a result of pressure differences.
Reason-Water, Minerals and food are generally moved by mass flow.
A)Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B)Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
C)Assertion is correct but Reason is incorrect.
D)Both Assertion and Reason are incorrect

Answer 1

Hint: Mass flow, also understood as “mass transfer” or “bulk flow”, is the action of fluids down a tension or temperature slope, extremely in the life sciences. As such, mass flow is a topic of research in both liquid dynamo and biology.

Complete answer:
Mass or bulk flow is the activity of materials in bulk from basis to sink as an outcome of tension differences. Fluids (water, elements, and food) are commonly shifted by mass flow.
The reason for bulk flow is usually tension or temperature slant.
Examples of mass flow encompass blood circulation and carrier of water in vascular plant tissues. Mass flow is not to be disturbed with distribution which depends on attention gradients within a moderate rather than tension gradients of the intermediate itself.

Option B: Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion. Therefore this is the correct option.

All other options are irrelevant.

Additional Information: Examples of mass flow comprise blood circulation and conveyance of water in vascular plant tissues. Immediate mass flow distribution is an important growth across enterprise as it abolishes inaccuracies resulting from the biological properties of the liquid, not smallest being the distinction among mass flow and volumetric progression.

Hence, the correct answer is option (B)

Note: In general, bulk progression in plant biology commonly pertains to the tendency of water from the soil up through the plant to the leaflet tissue through xylem, but can furthermore be pertained to the transport of huger solutes (e.g. sucrose) by the phloem.
Mass flow calculates the amount of particles in a flowing gas.
