The various bare-assed colors that appeared were taken note of and compared. Limiting Factors Planning A- The end of this experiment was to identify the presence of starch in ii different types of leaves through two types of methods. Two limiting factors, chlorophyl and light, were observed.

Qualitative measuring stick was done to measure how oft starch, if any at all, was produced and how the flip-flop reacted to light. Planning B- Both plants, the flame nettle and plant #2 , were starved of light and destarched for 7! 2 hours. After organism starved, a stencil was applied to a leaf from plant #2 which was then attached to a lamp.
