Widely accepted theory that explain transport of organic solutes in plants is supported by:
Correct answer: A. Preasure flow theory
- A. Preasure flow theory
- B. Diffusion
- C. Imbition
- D. Ascent of sap
Explanation
The widely accepted theory that explains the transport of organic solutes in plants is the Pressure Flow Theory, also known as the Mass Flow Hypothesis. This theory describes how sugars (mainly sucrose) are transported from source tissues (where they are produced, usually leaves) to sink tissues (where they are utilized or stored, such as roots, fruits, or storage organs) through the phloem.

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.
