Biology Coursework Analysis and Evaluation (transpiration)

Analysis - After doing this investigate, I can see from my graphical record that a mitigate in turn on inspiration 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 lifelike light on the plant at the beginning of the experiment water pronto evaporated. This is excessively due to the fact that snap water is also needed to aid in photosynthesis and to inhabit 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 evaporates from the spongy cells in leaves into the air spaces. Next, the water vapour diffuses finished 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 wat er. My results agree with my shot because transpiration did increase when the light intensity did. My graph upgrade appearinged my prescience to be accurate. Evaluation - The method that I use proved to be quite accurate because it helped me to make a relevant mop up about the factor ins change the rate of transpiration.

My results were accurate enough to show that there was unanimous 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 forward from the light. This result could have come about by a mistake in placing the lamp. At some gratuitys in the experiment I noti! ced that the base of my lamp was on the point plainly the actual bulb was still much ambient to the plant...
