Translocation of sucrose is between:
Correct answer: C. source to sink
- A. Sink to source
- B. Sink to sink
- C. source to sink
- D. Source to source
Explanation
Translocation of sucrose in plants primarily occurs from source to sink. In plants, the source is typically a region where photosynthesis occurs and produces sugars (usually the leaves), while the sink is a region where sugars are needed or stored (such as roots, developing fruits, or storage organs). Sucrose is transported through the phloem from the source to the sink to provide energy and nutrients to various parts of the plant.

About Circulation
The circulatory system covers the chambers, valves and conducting pathway of the human heart, along with the cardiac cycle and control of heartbeat. It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
