For this experiment petri-dish A is fully exposed to the light source while petri-dish B is partially exposed to the light. Independent Variable: We have chosen our independent variable to be the amount of light exposed to the cress seeds. Our first petri-dish was allowed to be fully exposed to the light surrounding it‚ while the second was fully wrapped in black paper excluding a 0.5cm slit directed towards the sun. Dependent Variable: Our dependent variable is the reaction/actions to

Title: Rate of transpiration I found interesting to know how different environmental factors affect the rate of transpiration. There are different environmental factors‚ such as light intensity‚ humidity‚ wind and temperature that affect the rate of transpiration. Transpiration is a topic 9 in our Biology higher level book. I have read all the information through this chapter and researched some extra information. Based on this information that I had known I decided to take experiment of environmental
