Crazy About Green Tomatoes. We've been growing our tomatoes upside-down for the past three years and really have fun growing them this way! We also grow tomatoes in the ground, and, by comparison, the ones in the upside-down buckets seem to have a little better yield than the same varieties grown in the ground.razy About Green Tomatoes.

Water is absorbed at the roots by osmosis, and any dissolved mineral nutrients travel with it through the xylem. The rate of transpiration is directly related to the evaporation of water molecules from plant surface, especially from the surface openings, or stoma, on leaves.
Xylem, which transports water and dissolved minerals, runs from the roots up through the stems and up to the stomates. Refer to your text to familiarize yourself with diagrams of xylem and phloem in typical plant roots and stems. The process of water movement through xylem and out the stomates is known as transpiration.. Transpiration and the Vascular System About 1% of the water taken up by plants is used for metabolic functions such as photosynthesis. The other 119% exits without ever being used by the plant. This process, known as transpiration, is ecologically vital, however.
