5.4 The Discovery of Auxin

This week we continue our systematic review of a plant's sensory systems by exploring the 6th sense - proprioception. We start with an overview of the proprioceptive system that allows us to keep our balance and to know where are body parts are in space. Theמ we will explore how plants know up from down, using both experiments from a few hundred years ago, and experiments conducted on the space station. We'll go over the structure of roots more in detail in order to understand where the cells are that sense gravity. We'll revisit phototropism, and learn what the chemical signal is in plants that allows them to respond to light and gravity. And lastly, we'll learn what makes a plant dance.
