The distance from the unsanded dot to the original dot was metrical in centimeters. The various bleak colors that appeared were payoffn quality of and compared.

qualitative measuring was done to heartbeat how much starch, if any at all, was produced and how the tack reacted to light. Planning B- Both plants, the coleus and plant #2, were starved of light and destarched for 72 hours.
