Comparing and contrasting the nature of cell signalling employed by plant cells and by animal cells. Both plant and animal cells inhabit complex communities, consisting of various tissues, and amalgamated into individual organisms. Such concentration of cells requires a high level of organisation and an effective means of communication. Consequently multicellular life has evolved intricate means of cellular communication, and despite the morphological differences, plants and animals share many similarities in the way they communicate. In both plants and animals signalling between cells involves six basic steps. Primarily a signalling molecule is synthesised (step 1), then it is released from it's signalling cell (step 2) and transported to the target cell (step 3). At the target cell specific receptor proteins detect the signal (step 4), which triggers a change in cell operations (step 5) and finishes with the removal of the signal (step 6).
