Plant Growth Factors

HideShow resource information

Plants do not have a nervous or circulatory system, so are limited in how they communicate with separate parts of the plant. However, coordination is still important for plants, as it allows them to respond to a changing environment, making survival more likely. They do this coordination by Growth Factors. Growth factors allow tropic responses to be carried out, such as phototropism, geotropism and hydrotropism

A growth factor is similar to a hormone in ammals, apart from a few key differences:

  • Growth factors influence the plant by affecting the rate of growth in different parts of the plant.
  • They are made…
