Detailed explanation-1: -When the guard cells are swollen, stomata is sealed causing less water loss through transpiration. Leaf hair – It deflects some light and maintains a cool plant temperature causing minimal loss of water.
Detailed explanation-2: -Increased humidity has a reduces transpiration. The lower the humidity the easier it is for the plant to release water. The type of plant is also a factor in how much a plant will transpire. For example plants grow in arid hot areas such as the desert will transpire less as they aim to conserve water.
Detailed explanation-3: -Leaves that possess many hairs or pubescence will have larger boundary layers; the hairs serve as mini-wind breaks by increasing the layer of still air around the leaf surface and slowing transpiration rates.
