Plants, Transpiration, Photosynthesis and Respiration
TranspirationCritical Thinking:1. Do you think plants would lose more water to
transpiration in windy conditions or non-windy conditions?
2. Do you think plants would lose more water to transpiration in humid conditions or dry conditions? Why?
3. Explain how plant transpiration contributes to the water cycle.
4. Where on Earth would you find the most transpiration? Why? Do you think this has an effect on climate?
5. What would be the effect if humans were to plant a huge number of leafy trees in one county of North Carolina. They would plant so many there they would cover the land. Do you think conditions there would be different? Why or why not?
Transpiration—stoma are small openings on the underside of leaves which are used for gas exchange, (O2 & CO2). Guard cells on each side help open & close stoma. Plants also lose water through the stoma. So, stoma are usually closed during the hottest part of the day so they don’t lose so much water. Plants only use about 10% of the water they absorb from the Earth. The rest is released into the atmosphere through transpiration.
2. Use the information from the article to Explain why it is important for an aquarium owner to be very careful in how s/he sets up his or her aquarium.
