Question

Assertion : The process of loading at the source produces a hypotonic condition in the phloem.

Reason : That is the reason the phloem sap moves towards the sink.

• A. if both A and R are true and R is the correct explanation of A
• B. if both A and R are true but R is not the correct explanation of A
• C. if A is true but R is false
• D. if both A and R are false.

Answer 1

The correct option is D

if both A and R are false.

Vein loading causes the source to become hypertonic and this helps in the translocation towards the sink.
