How do plants convey information about a touch from one cell to another?
Show answer & explanation
Correct answer: C
Explanation
Information Transmission in Plants -
Although plants lack a nervous system like animals, they still respond to external stimuli (such as touch).
Electrochemical Mechanisms: When we touch the leaves of a plant (such as Mimosa pudica), the cells transmit this information from one cell to another using electrochemical signals.
Cell Shape Changes: Upon receiving information, plant cells change their shape by changing the amount of water they contain. When water is released, the cells shrink, causing the leaves to bend or close.
Plasmodesmata: These small pathways between cells help in the flow of information and chemicals.
