"...biological awareness suffuses the whole plant body. As any plant grows, it builds its body to suit its environment, both in root and shoot. The shape that emerges is a direct response to the physical obstacles it encountered, the distribution of nutrients in the soil, and the direction of light. In this way a plant's entire body is a physical expression of the conditions, moment to moment, over the whole story of its life...In our brains, a memory is a physical entity, a connection between neurons. In plants, memory may be physical pathways too... the lobe on a trunk where a branch once existed tells the story of sunlight since shaded out." - The Light Eaters, Zoë Schlanger
