Leaves "give off" water or "transpire" in some ways similar to
how people "give off" water or "perspire" or "sweat." Plants
need water to grow and make food in the process
called "photosynthesis." Carbon dioxide (in the air) + water +
sunlight energy = food (a sugar called glucose) + oxygen (in
the air).
