Question

Translocation of organic materials in plants is explained by

• A. Active transport
• B. Transpiration pull
• C. Inhibition theory
• D. Mass flow hypothesis

Answer 1

The correct option is A Active transport

Active transport is the mediated transport of biochemicals, and other atomic/ molecular substances, across membranes. Unlike passive transport, this process requires chemical energy in the form of adenosine triphosphate (ATP). In this form of transport, molecules move against either an electrical or concentration gradient (collectively termed an electrochemical gradient).
