Interesting, I wonder how that'll contribute to the snowball effect of global warming since as it gets hotter I'm sure they'll perspire more.
- vkou 7y agoPlants solve prespiration by bringing water from their roots, up to their leaves. They burn sugars for energy they need to live, not for water they need to stay cool. Sugars are difficult to make, water can just be pulled directly from their environment. So, it won't be a noticeable effect.
- im3w1l 7y agoPlants work on a similar principle as human nutrition. CO2 in - CO2 out = weight gain. A growing plant is on average* a net absorber of carbon dioxide. * On average, not constantly. Since they can't do photosynthesis in the dark, they release CO2 at night.
