Plants have stomata. These are small holes which are used for gas exchange during photosynthesis. However, this stomata also cause water to diffuse and evaporate out of the plant, when photosynthesis is occurring, meaning water is lost. This water vapour which is lost is given out to the surrounding air, increasing the humidity (which is just water vapour). This loss of water causes more water to be drawn up from the roots through the xylem tube networks, giving a constant stream of water. This is called Transpiration.

The amount of water vapor in the atmosphere is known as what term?

The amount of water vapor in the atmosphere is known as humidity. Humidity can be expressed as specific humidity, relative humidity, or absolute humidity depending on the context.


What is the difference between relative humidity and humidity, and how do they impact the environment?

Relative humidity is the amount of water vapor present in the air compared to the maximum amount the air can hold at a specific temperature. Humidity, on the other hand, refers to the overall amount of water vapor in the air. Both relative humidity and humidity can impact the environment by affecting temperature regulation, precipitation, and the growth of plants and organisms. Changes in humidity levels can influence weather patterns and ecosystems.
