Detailed explanation-1: -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-2: -Cool conditions, no wind and humidity slow down transpiration rate.
Detailed explanation-3: -Direct sunlight warms up the leaves and causes the stomata to open, thus, more transpiration occurs during the day. The transpiration rate is higher on a sunny day compared to a cold dull day.
Detailed explanation-4: -Temperature-as temperature increases, so does the rate of transpiration. The lower the temperatures, the lower the transpiration rate. Guard cells tend to close the stomata in windy conditions to prevent that. Wind-generates more water loss because they lead to higher evaporation rates.
