  This paper considers an electro-chemical based communication model for
intercellular communication in plants. Many plants, such as Mimosa pudica (the
"sensitive plant"), employ electrochemical signals known as action potentials
(APs) for communication purposes. In this paper we present a simple model for
action potential generation. We make use of the concepts from molecular
communication to explain the underlying process of information transfer in a
plant. Using the information-theoretic analysis, we compute the mutual
information between the input and output in this work. The key aim is to study
the variations in the information propagation speed for varying number of plant
cells for one simple case. Furthermore we study the impact of the AP signal on
the mutual information and information propagation speed. We aim to explore
further that how the growth rate in plants can impact the information transfer
rate and vice versa.
