Report Objective: - To study the transpiration rate of a plant (Gou Qi) by using the bubble photometer. Assumption: - The rate of transpiration is equal to the rate of water uptake of the plant(Gou Qi) . Theory: |Independent Variable |Dependent Variable |Controlled Variable | |The environmental conditions: | Rate of water uptake by transpiration of the |Time taken for the movement

Adriana Rempson Mrs. Steeger AP Biology-7 10 October 2012 Transpiration in Plants Abstract: Our group wanted to see how transpiration would happen in plants when they were in different environments. The different environments we used were humidity and room environments. We measured transpiration using the whole plant method. Our results showed that the plants in a humid environment had greater transpiration rates than the plants in the room environment. Introduction: Pants absorb and

hairs (via osmosis & root pressure) Move through cortex into xylem (small xylem vessels) via symplastic loading (movement through cell) & apoplastic loading (movement through cell wall) Water movement up xylem by capillarity Stomata controls transpiration allowing water to leave xylem into leaf water in leaves Mesophyll cells – cells in leaves specialised for photosynthesis. Walls are moist – air spaces around them contain water. Gases enter & leave leaf through stomata – when sun shines‚

Required materials All purpose flour Water Jar with a lid Spoon Brush Newspaper Estimated Experiment Time Less than 5 minutes to make the glue‚ about 15 minutes for it to dry (when applied) Step-By-Step Procedure 1. Mix one cup of flour with one-half a cup of water together in the jar. Use the spoon to make sure the mixture is stirred well. This will become your glue. 2. Use your glue mixture to glue the newspaper into various shapes. Do this by brushing the glue onto the newspaper and

dark environments on transpiration. If the wind speed is high enough during the night time will this cause the opening of stomata and transpiration‚ even though it is against the plants bioloical clock to do so? I’ve got 3 different wind speeds on the fan and I’m keeping the temperature constant in both light/dark environments. Wind speed does not normally cause stomata to open. Indeed‚ high wind speed may cause stomata to close a) because of the high rate of transpiration leading to water stress
