Biology - December 2007

Recently we did a self designed lab in which we were to select a variable (sunlight soap) and conduct research whether it affects the plant growth or not. Amazingly enough it did so, but now i have no clue which chemical inside the (sunlight liquid soap) could affect plant's growth, and how could it cause to get very nonrigid and eventually die?

please help!
