Vapor Escape

We do get hydrogen from the solar wind, and our magnetic field ram scoops more hydrogen from the solar wind.

Why is transpiration so important? Besides cooling the plant, transpiration drives its “circulatory system.” Imagine a vein at the tip of a leaf. Through the intricate network of vascular tissues, this leaf is connected to the roots—similar to the way the capillaries in your fingertips are connected to your heart. In humans, the force driving circulation is the heartbeat; in plants, it’s transpiration. Water vapor escaping the leaf surface creates a tension that draws more water up to replace it. Through the network of veins, this process occurs in every leaf throughout the entire plant.

During photosynthesis, the stomata must open to take in carbon dioxide. But when the stomata are open, water vapor from the area around the spongy cells escapes into the surrounding air. The evaporation and release of water vapor cools the leaf surfaces, in much the same way that the evaporation of perspiration cools our bodies. (Think of how much cooler and more humid it is in a thick, lush forest. All those plants are releasing water vapor as they photosynthesize.) However, this evaporation also drives some other very important functions.

Plant tissues are generally moist inside. Leaf tissues contain lots of water—in the form of both liquid and vapor. Remember that layer of spongy cells in the mesophyll? The spaces between those cells is where all sorts of gas exchanges take place, as oxygen and carbon dioxide gases are formed and consumed. Those spaces also contain water vapor that has evaporated from the moist surfaces of the cells.
