Ms. Blankenship’s tenth grade class is studying the impact of photoperiod on plant growth. Her students fill 100 paper cups with potting soil and a single pea seed. Each cup is randomly assigned to one of four growth chambers. Each of the four growth chambers has an identical artificial light source (25 watts) but each has a different light (L) : dark cycle (D). Chamber 1 is set to 24L : 0D. Chamber 2 is set to 16L : 8D....
