easy · Enhanced ACT science
Three identical seeds were each given a different amount of daily light, and the height of each seedling after two weeks was recorded:
Plant X: 4 hours light/day, final height 6 cm
Plant Y: 8 hours light/day, final height 11 cm
Plant Z: 12 hours light/day, final height 17 cm
Which plant grew to the greatest height?
- Plant X
- Plant Y
- Plant Z
- All three reached the same height
