Biology Coursework Analysis and Evaluation (transpiration)

Analysis - After doing this try out, I can see from my graphical record that a mitigate in fire up lastingness reduces the enumerate of transpiration. This is because when there is a high level of light intensity it starts to evaporate either water and because there was such enthusiastic light on the plant at the beginning of the taste water pronto evaporated. This is excessively due to the fact that alternate water is also needed to aid in photosynthesis and to engine block the leaves from wilting. Transpiration takes channelize more during the day than it does at night because light causes the stomata to open and when they be open water is lost faster. water supply evaporates from the spongy cells in leaves into the air spaces. Next, the water vapour diffuses through and through the stomata into the air. The process of transpiration takes place to continuously draw water up the xylem from the roots. This water is then(prenominal) drawn into the spongy cells to replace the lost water. My results concur with my shot because transpiration did increase when the light intensity did. My graph throw out appearinged my prescience to be accurate. Evaluation - The method that I employ proved to be quite accurate because it helped me to make a relevant mop up about the factor ins modify the rate of transpiration.

My results were accurate enough to show that there was real correlation between the possible factor (light intensity) and the rate of transpiration. In my results there was only 1 anomalous result, which was at 40cm remote from the light. This result could have come about by a mistake in placing the lamp. At ! some gratuitys in the experiment I noticed that the base of my lamp was on the point except the actual bulb was still much ambient to the plant...
