To Study the Transpiration Rate of a Plant (Gou Qi) by Using the Bubble Photometer.

Biology 1st Group Lab 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 of the air bubble |
|Normal |plant(Gou Qi) |(5MIN -> 10MIN) |
|Higher light intensity | |Type of the plant(Gou Qi). |
|Greater air movement | | |
