Plant hormonal regulation differs from animal hormonal regulation in that plant hormonal regulation differs from animal hormonal regulation in that only animal hormone concentrations are developmentally regulated all production of hormones is local in plants with little long-distance transport only animal hormones may have either external or internal receptors there are no dedicated hormone-producing organs in plants as there are in animals

I believe that plant hormonal control differs from animal hormonal control in that there are no separate hormone-producing organs in plants as there are in animals.  Hormones regulate cellular processes in targeted cells locally and moved to other locations, in other function parts of the plant. Hormones also determine the formation of flowers, stems, leaves, the shedding of leaves, and the development and ripening of fruit. Plants unlike animals they lack glands that produce and secrete hormones and instead each cell is capable of producing hormones.
