Question

Which of the following is NOT a sink?

• A. roots
• B. developing fruit
• C. apical meristem
• D. none of the above

Answer 1

The correct option is D

none of the above

Roots are food storage organs and hence food is transported to them from the leaves. Hence roots are sinks. Also, all young growing parts are considered as sinks as they have the highest rate of metabolism and hence require food. Developing fruits and the apical meristem are growing parts, and hence act as sinks.
