Mechanisms of Plant Growth
We've gone over the various tiers of structure of a plant, from cells, to tissues, to organs and organ systems. Now it's time to better understand how plants grow. How to plants know when to grow? How do they know which direction to grow? All of this is regulated by plant hormones, which are signaling molecules, just like the ones that we have ...

SOLVED:Transpiration is fastest when humidity is low and temperature is high, but in some plants it seems to increase in response to light as well. During one 12 -hour period when cloud cover and light intensity varied frequently, a scientist studying a certain crop plant recorded the data in the table (top right). (The transpiration rates are grams of water per square meter of leaf area per hour.) Do these data support the hypothesis that the plants transpire more when the light is more intense
