“Water leaving a plant through transpiration doesn’t just leave; it creates by its leaving a force called transpirational pull, which both draws more water into the plant through its roots and provides for water movement within plant tissues. Plants don’t have a heart the way humans and other animals do. Transpiration is the plant’s substitute for a heart; it is the way a plant moves fluids within itself. Without transpiration, plants could not move water and nutrients from the soil, could not make sugars through the miracle of photosynthesis, could not move those sugars about and change them into starches – could not, in short, grow, mature, fruit, and produce seeds.”
– The Vegetable Gardner’sContainer Bible by Edward C. Smith
