The chemical messenger that transports signals from one cell to another, called phytohormones in plants, are called what in animals?
Plant hormone Plant hormone Plant hormones (also known as phytohormones) are signal molecules produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of growth and development, from embryogenesis, the regulation of organ size, pathogen defense, stress tolerance and through to reproductive development. Unlike in animals (in which hormone production is restricted to specialized glands) each plant cell is capable of producing hormones. The term 'phytohormone' was coined by Went and Thimann and used in the title of their book in 1937. Phytohormones are found across the plant kingdom, and even in algae, where they have similar functions
Mimicry in plants of signals. Cryptic mimicry in plants is usually achieved visually. The South American "Boquila trifoliata", of the Lardizabalaceae family, is a climbing vine with a highly variable phenotype. It is capable of mimicking the leaf features of plant species that it clings to, adopting color shape and size. By camouflaging its leafy appendages, "Boquila" lowers its rate of herbivory. Mimicry in plants In evolutionary biology, mimicry in plants is where a plant organism evolves to resemble another organism physically or chemically, increasing the mimic's Darwinian fitness. Mimicry in plants has been studied far less than mimicry in animals, with fewer
