"WebbThere are differences between plant and animal hormones. For example, animal hormones are synthesised in particular organs or tissues, and by definition they act in different places to where they are produced. This is not necessarily true for phytohormones; some exert their action in exactly the same place where they are synthesised. " - Phytohormones examples
