The process of transpiration has multiple stages. First of all plants have Xylems this allows the plant to transport water around to the roots to the shoots and leaves of the plant. Plants have dead Xylems as well because they can store more water capacity. When the water is stored and the plant is ready to transpire, it can by making the water evaporate from the leaves in the plant to the air.

Transpiration occurs briefly at the leaves when the stomata allows the passage of Carbon Dioxide and Oxygen during the process of photosynthesis. This allows gas exchange between the atmosphere and the leaves.

There are four factors that can affect transpiration these are Light,Wind,Temperature and Relative Humidity. Light will affect transpiration in plants because the stomata normally opens when there is light so in daytime if there is no light it will not open so the process of transpiration will not carry out.Wind will affect transpiration by removing thin layers of moist air so the process can go faster. Temperature affects transpiration of plants because when the temperature is at 20 degrees celsius to 30 degrees celsius the process will be the fastest and if not then it will be a little slower and you want the process to be fast. Lastly Relative Humidity affects transpiration because when the Relative Humidity is high the stomata closes so the process cannot happen therefore we need the Relative Humidity to be normal so it can happen. These were the four factors.
