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.
Save. Water moves upward through a plant through the xylem tissue. Along with water, xylem also transports dissolved minerals, and some small organic molecules. This fluid mixture of materials flowing through the xylem is called sap.ater enters the roots through diffusion or osmosis. The root has a higher salt concentration on the plant side of the membrane than in the soil. Water flows from the low salt side to the high salt side trying to make the salt concentration equal. The root does not allow passive movement of salts across the membrane.
