This was complexed by the fact that the leaves because thicker to prevent moisture loss. The gaurd cells which open and close the stomata is a huge adaptation to solve these problems. To transport nutrients throughout the plant, the xylem and phloem were developed. 12) Above water, there is nothing to support the plant, so a crude skeletal system was adopted.
