WebOct 5, 2024 · The hydrogen in water goes to form carbohydrates—sugar, the food for the tree. The oxygen is exhaled through pores in the leaves. Water also evaporates, or transpires, through these pores. It’s this transpiration from the leaves that pulls water up the trunk and branches to them. Now, that’s a long way to lift it, so the water itself helps. WebSep 28, 2024 · On Earth, plants draw water upwards through the roots against gravity, via capillary action, which orients the plant and enables display of its canopy (foliage and branches) for optimal photosynthesis and transpiration. The plant grows above the nutrient-rich soil as the water recedes into the soil, and oxygen from the air between the soil ...
