Question

A plant uses .......... means to transfer information from one cell to another as there is no specialized tissue present for the conduction of information.

• A. Thermal
• B. Electrical
• C. Chemical
• D. Electrochemical

Answer 1

The correct option is D Electrochemical

The most rapid methods of long distance communication between plant tissues and organs are bioelectrochemical signals. The action potential propagates rapidly throughout the plant along electrified interfaces. A potential pathway for transmission of this electrical signal might be the phloem sieve-tube system since it represents a continuum of plasma membranes. A phloem is an electrical conductor of bioelectrochemical impulses over long distances. At the cellular level in plants, electrical potentials exist across membranes, and thus between cellular compartments, as well as within specific compartments. Electrochemical phenomena are primary, and then deep cytophysiological reactions occur.

So, the correct answer is 'Electrochemical'.
