A decrease in the availability of ATP in a root cell could decrease the water potential of the cell.
Answer the following statement true (T) or false (F)
False
A lack of ATP in a root cell would affect the cell's ability to actively pump ions into the cell from the soil. Without these ions, the water potential of the cell would increase and make it more difficult for the root hair to absorb water. The movement of water is dependent on the soil having a higher water potential than the root hair so that water will move into the plant via osmosis.
