The vascular tissue contains xylem cells, which are important for transpiration because the xylem cells allow the water to move against gravity to reach the uppermost leaves in the plant. The stomata are important for transpiration because they contain guard cells that control the amount of water that can enter and exit the plant. This is important because in hot conditions the guard cells close up and becomes turgid to prevent water loss because they cannot afford to lose too much water to the environment and in cold conditions the guard cells open up and lose water so they become flaccid. 4 ...
