What is transpiration in the water cycle short answer?
Transpiration: The release of water from plant leaves Plants put down roots into the soil to draw water and nutrients up into the stems and leaves. Some of this water is returned to the air by transpiration.
How does evaporation and transpiration contribute to the hydrologic cycle?
Evaporation is when water vapor comes from liquid surface water, such as streams, lakes, rivers, and oceans. Like boiling a pot of water, heat from the sun energizes the water on the surface, which turns it from liquid to gas. Transpiration is when water vapor comes from liquid water excreted by plants.
How does transpiration play a role in the water cycle?
Transpiration helps in the process of photosynthesis and exchange of gases. In the water cycle, it plays a major role as approximately 10% of total water which is present in the atmosphere is because of the transpiration process.
How does water move through the plant during transpiration?
Water moves through the plant due to capillary action — which can pull liquids through narrow tubes like the stems — and transpiration. Water that is pulled through the stem by capillary action then makes its way up to the flower and leaves. Once in the leaves and petals, the water evaporates in a process called transpiration.
Why is transpiration so important?
Transpiration is the loss of excess water from the surface of the leaves, it is important because transpiration helps the plant reduce temperature in deserts, regulating the plant’s temperature and also keeps the plant fresh.
What happens to runoff in the water cycle?
The runoff stage of the water cycle. Runoff is precipitation that did not get (infiltrated) absorbed into the soil or did not evaporate, and therefore, made its way from the ground surface into places that water collect. It can cause water pollution too. Only about 35% of precipitation ends up in the sea or ocean.
