Dew comes from condensation in the air, while guttation comes from the water in the soil. Plants also use stomata for photosynthesis, and since photosynthesis doesn't happen at night (it can't happen without the sun, after all), the stomata close shop. Can you explain this answer? While the drops of xylem look like dew, they're very different. Guttation is when a plant pushes water out through tips of the leaves of plants. - Definition, Function & Products, CSET Science Subtest II Life Sciences (217): Practice & Study Guide, UExcel Anatomy & Physiology: Study Guide & Test Prep.
