How do plants use and release water

Answer #1

Transpiration: The release of water from plant leaves

Just as you release water vapor when you breath, plants do, too – although the term “transpire” is more appropriate than “breath.” This picture shows water vapor transpired from plant leaves after a plastic bag has been tied around the stem for about an hour. If the bag had been wrapped around the soil below it, too, then even more water vapor would have been released, as water also evaporates from the soil.

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. Transpiration rates vary widely depending on weather conditions, such as temperature, humidity, sunlight availability and intensity, precipitation, soil type and saturation, wind, and land slope. During dry periods, transpiration can contribute to the loss of moisture in the upper soil zone, which can have an effect on vegetation and food-crop fields.

How much water do plants transpire? Plant transpiration is pretty much an invisible proces – since the water is evaporating from the leaf surfaces, you don’t just go out and see the leaves “breathing”. Just because you can’t see the water doesn’t mean it is not being put into the air, though. One way to visualize transpiration is to put a plastic bag around some plant leaves. As this picture shows, transpired water will condense on the inside of the bag. During a growing season, a leaf will transpire many times more water than its own weight. An acre of corn gives off about 3,000-4,000 gallons (11,400-15,100 liters) of water each day, and a large oak tree can transpire 40,000 gallons (151,000 liters) per year.

Answer #2

not sure, but it’s called transpiration. try looking it up on google or wikipedia.

Answer #3

They transpire the water to keep cool.

Answer #4

they transpire water so that a optimum temperature can be kept inside the plant and they can absorb minearls and ions from the soil
