The biggest challenges of being a plant are that they can’t go inside when it gets too hot or too cold, they can’t move around till they find something to eat, they can’t pick up and leave when there is nothing left to drink where they currently are, and when a bug comes to eat them, they can’t call an Uber. Rather, plants have to figure out how to take light from the sun, carbon dioxide from the air, and water and nutrients from the soil under the often really tough environmental conditions of where the seed that produced them happen to sprout. Plants have to figure out how to do this in a desert when it is really hot, or in the alpine, where it is really cold. They have to figure out how to do this when there is almost no light when they are trying to grow at the bottom of a tropical rainforest, or when there is too much light (yes, avoiding sunburn is a real problem for plants too!). Plants have evolved an amazing array of physiological processes and adaptations that allow them to not only cope with the many challenges of the earth’s diverse environments, but to prosper in the most brutal of climates, to make the world the green place we see when we step outside, and to be the fundamental source of food for our existence. And as if they don’t have enough to do just to survive, plants serve on the front line of fighting back against the human-caused rise of carbon dioxide in the atmosphere that is driving global climate change.
